Answers To Additional Cytokine Analysis, Biomarker Assay Questions Popular Among Our Potential Clients.
Cytokine assays measure levels or activities of cytokines, which are small proteins that regulate the immune system and its response to diseases and treatments. Cytokine assays are essential for studying immune function, inflammation, infection, autoimmunity, allergy, cancer, transplantation, and other immunological disorders.
Multiplex cytokine assays enable the simultaneous quantification of multiple cytokines in a sample using technologies such as a planar array or bead-based platforms. Multiplex cytokine assays can save time, cost, and sample volume and provide a comprehensive profile of the cytokine network and its changes in response to stimuli.
Some of the latest platforms and technologies for performing cytokine assay services include:
We offer various cytokine assay services, such as custom or pre-designed assays, biomarker method development and validation, sample analysis, data analysis and interpretation, and report generation. We can help you to choose the best cytokine assay platform and format for your research needs and sample types and to optimize and validate the assay conditions and performance. We can also provide you with graphical representations of the data, including scatter plots, bar charts, or heat maps.
To determine the correct sample type and volume for cytokine testing services, consider the assay platform, format, sensitivity, cytokine expression levels, and stability in different matrices. Some common sample types for cytokine testing services are plasma, serum, cell culture supernatants, PBMC, urine, tissue lysates, cell lysates, and CSF. The sample volume depends on the number of cytokines to be measured, the assay sensitivity, and the dilution factor. Generally, the sample volume ranges from 25 to 100 μL per well.
Cytokine profiling provides a comprehensive overview of the cytokine network and its changes in response to different stimuli, such as antigens, drugs, or infections. Cytokine profiling can help to understand the immune response, the mechanism of action, and the efficacy of drugs and immune modulators. Cytokine profiling can also help to discover and validate novel biomarkers, monitor therapeutic responses and adverse effects, and study gene regulation and function.
Cytokine testing helps to understand the cell signaling pathways and mechanisms of action of drugs and immune modulators. Cytokine quantification can measure the expression levels of cytokines and their receptors and the activation of downstream signaling molecules, such as transcription factors, kinases, or phosphatases. Cytokine testing can also help to study the interactions and networks of cytokines and other immune mediators, such as chemokines, growth factors, and receptors.
Cytokine expression assay can help measure cytokine levels and activities. Some of the most common applications of cytokine expression assay are:
Cytokine assays can be used for:
The advantages and disadvantages of different platforms for cytokine screening assays, such as ELISA, Meso Scale Discovery, Luminex multiplex, etc., depend on the assays’ sensitivity, specificity, throughput, cost, and reproducibility. ELISA is a simple and widely used platform for cytokine screening assays. Still, it has low sensitivity, specificity, and throughput, and it requires a large sample volume and a separate assay for each cytokine. Meso Scale Discovery is a platform that uses electrochemiluminescence to detect cytokines. It has high sensitivity, specificity, and throughput but is expensive and requires specialized equipment and reagents. Luminex multiplex is a platform that uses bead-based or planar array technologies to detect multiple cytokines in a single sample. It has high sensitivity, specificity, and throughput but is expensive, requires specialized equipment and reagents, and may have interference or cross-reactivity issues.
Biomarker testing services provide a powerful approach to measuring biological process indicators in normal and pathological conditions or in response to pharmacological intervention. Biomarker analysis in blood or other bodily fluids at either the DNA or protein level has been used by physicians for decades to study human diseases. Physicians readily rely on biomarker services to diagnose and manage clinical conditions such as cardiovascular diseases, cancer, immune responses, and genetic disorders. However, the application of biomarker assay in research has recently exploded out of a desire to gain crucial information about biological reactions upon exposure to novel therapeutic compounds.
Clinical biomarkers in drug discovery and development are crucial at all phases, from drug discovery to first in human trials. Biomarker assay services are used extensively in the earlier stages of the drug discovery process for mechanistic or pharmacodynamic purposes such as determining the mechanism of action, validating drug targets, monitoring therapeutic responses, and guiding compound selections. Thus, early biomarker analysis services measure biological response and helps decide whether potential therapeutic agents should be pursued further or discontinued. Later in the drug development process, biomarker testing is expanded to include clinical biomarker services for patient screening and treatment. These clinical studies include diagnostic, prognostic, and safety biomarker lab services to examine patient populations, patient risks/responses to treatment, and clinical endpoints.
For example, biomarker testing services have been used extensively in drug discovery for cancer resulting from the changes in a cell’s genetic material. Specifically, biomarker analysis services have been used to quantitate these inter and intracellular changes associated with various cancers. One use of biomarker services for cancer lies in evaluating the impact of a drug/compound on cancer cells’ growth. Scientists assess genomic changes, abnormal features, or biochemical effects of the tumor during cancer’s biomarker assay testing to identify the disease’s reproducible signs. Biomarker analysis relies on correlating markers identified previously to categorize samples by disease stage or treatment efficacy.
As a nimble Biomarker CRO, we offer singleplex or multiplex assays on the MSD or Luminex platforms or as commercially available ELISA assays evaluated using a traditional 96 well plate format. All these assays undergo a fit for purpose biomarker validation, including assessing bioanalytical parameters such as accuracy, precision, and sensitivity.

As a GLP certified CRO specializing in biomarker assay development, we maintain high-quality standards that meet our sponsor and regulatory agency needs. Some of our most popular biomarker assay services include assay development, method validation, and cytokine testing.
Biomarker assay development and validation are crucial in establishing a robust bioanalytical method to quantify a specific biological response in our chosen biological matrix. Afterward, biomarker analysis plays a significant role in assessing the efficacy and safety of novel or repurposed therapeutic compounds. US FDA and other regulatory agencies require fit for purpose (FFP) biomarker validation and assay characterization depending on expected context of use (COU) to ensure data integrity and reproducibility fundamental to each clinical trial’s success.
Biomarker assay development begins by examining the biomarker of interest, selecting a suitable analysis platform, and surveying available or made-to-order materials such as kits, recombinant or natural reference proteins, capture/detection antibody pairs, diluents, buffers, substrates, reagents, control matrices, etc. Next, we perform a pre-validation test run of the biomarker assay with calibration standards and quality controls to analyze a few sponsor samples in duplicate. Once the preliminary biomarker development is complete, our team of expert scientists performs proper validation for each of your biomarker services to demonstrate method reliability for the intended use.
For early drug development, such as compound selection or proof of concept, the extent of biomarker validation depends on sponsor preference. Generally, US FDA recommends full biomarker assay validation if the study results will inform regulatory decision-making, such as ascertaining drug safety or product labeling. Per FDA biomarker method validation guidance, we must evaluate all critical assay parameters to lie within approved acceptance criteria for accuracy, precision, selectivity, sensitivity, dynamic range, etc. Furthermore, biomarker validation may also cover stability, parallelism, specificity, dilution effects, and prozone effect.
We hold extensive expertise in a wide range of biomarker assay development and validation services to meet your needs through all stages of the drug development process. Specifically, our biomarker assay services include custom assays using proprietary or commercially available antibodies, research use only (RUO) kits, and singleplex or multiplex MSD or Luminex assays.

Biomarkers are the indicators that measure the normal vs. abnormal biologic and pathogenic processes, as well as pharmacologic responses to therapeutic intervention in the body. Biomarker analysis plays a critical role in medical science to administer patient health and improve drug development. Scientists can measure the response of investigational drugs during preclinical studies and clinical trials with biomarker testing. For example, the life sciences community relies on several well-characterized biomarker assays to demonstrate expected clinical outcomes for various treatments. Thus, Biomarkers are useful in identifying the probability of disease recurrence or progression and predict the favorable or unfavorable response towards any treatment. Examples of biomarkers include:
Clinical biomarker testing assesses the impact of a drug/compound on the human body. Biomarkers are measurable indicators of biological processes in normal and pathological conditions, or in response to pharmacological intervention. Biomarkers are used extensively in the drug discovery process to evaluate the health of a person or the efficacy of a treatment. Biomarkers can be measured in any biological sample, such as tissue, bodily fluids, blood, etc. Biomarker testing occurs at all stages of the drug discovery process and allows scientists to identify robust biomarkers and accurately measure the state of that biomarker in any given individual.
Biomarker research is divided into three types based on the molecules being analyzed – gene, chromosome, and biochemical markers. Gene biomarker testing evaluates mutations within a gene and extra, missing, or incorrect copy number of genes. Chromosome testing analyzes changes at the chromosome level, including deleted, switched, or expanded chromosomal sequences. In biochemical biomarker testing, scientists measure changes in protein quantity or function.
Once biomarker method validation is achieved, the biomarker is utilized in drug development for disease identification and/or treatment options. Biomarker discovery is critical in concept and safety studies for drug development. During the initial phase of drug discovery and development, biomarker research helps in identifying a suitable dose range. This is achieved by evaluating the effect of a specific dose of a drug on the biomarker. Safety biomarkers, on the other hand, are essential to ensure the safe functioning of body organs, such as liver and kidneys, during drug treatment. Throughout drug development and the preclinical/clinical trials, biomarker analysis services helps in maintaining the safety profile and measuring the efficacy of a drug compound.
NorthEast BioLab offers an extensive biomarker menu for qualifying, developing, validating, analyzing, and multiplexing high-quality biomarker testing for large and small molecules. We use LC-MS/MS, ELISA, MSD, Luminex, Western Blot, and qPCR, among other platforms for customized and GLP-compliant biomarker analysis. The level of method validation for biomarker analysis is fit-for-purpose, such as whether we are working with i) exploratory biomarkers for pharmacodynamics information vs. ii) confirmatory biomarkers for pivotal determination of drug safety and efficacy. Given our 15+ years experience in biomarker analysis, we provide novel and established biomarker testing services in numerous biological species and matrices, including most bodily fluids and tissue homogenates.
NorthEast BioLab performs biomarker testing using LC-MS/MS, ELISA, MSD, Luminex, qPCR, and Western Blot, among other technologies. LC-MS/MS offers a highly sensitive and specific biomarker assay with multiplexing potential for a similar class of small molecules. ELISA is a versatile platform for biomarker analysis of large molecules such as proteins, peptides, antibodies, and hormones in the biological samples. Biomarker assay development commonly applies the three major ELISA types: Sandwich ELISA with matched antibody pair for complex and unpurified biological samples, Indirect ELISA for determining total concentration for multiple antibodies in the sample, and competitive ELISA for small antigens or when only one antibody is available.
Furthermore, our scientists offer testing from the entire biomarker menu of Meso Scale Discovery (MSD) and Luminex Multiplex kits to quantify 40+ analytes within the single sample. Advantages of biomarker analysis using these state-of-the-art multiplex platforms include –
Biomarker research can be performed on multiple platforms. Genetic biomarker analysis is carried out using DNA from bodily fluids or tissues. Biomarker labs use DNA sequencing, quantitative polymerase chain reaction (qPCR), microarray-based comparative genomic hybridization (CGH), and gene expression array. Cytogenetic biomarker testing commonly employs karyotyping and fluorescence in situ hybridization. Biochemical biomarker testing generally uses mass spectrometry techniques such as MALDI-TOF-MS and ESI-MS/MS, immunology techniques like MSD, Luminex multiplex, ELISA immunoassay, and Western blot. NorthEast BioLab offers LC-MS/MS, ELISA, MSD, Luminex, qPCR, and Western Blot platform for biomarker development and validation services.
The platforms for biomarker research and analysis are commonly categorized based on their purpose to examine exploratory biomarkers that are potential endpoints to be validated or confirmatory biomarkers that explain significant drug safety and efficacy. Biomarker development provides both diagnostic tools and contextual data interpretation in clinical research. For example, biomarker research platforms could measure therapeutic responses against drug treatment. These platforms can help screen the patient group that would likely have adverse effects from the therapy. Furthermore, biomarker CRO can measure the toxicity associated with drug treatment. Thus, clinical biomarker testing services are pivotal for drug development from establishing proof-of-concept (POC) in vivo to demonstrating drug potential in clinical trials.
Biomarker assays are essential for drug discovery and development as they aid in drug candidate selection and measure drug function. Since biomarker assay services offer the basis for early drug efficacy, it is imperative to select the right biomarker. We offer biomarker lab services for drug discovery, preclinical, and clinical phases.
Drug Discovery
It is possible to meaningfully accelerate drug development with the selection of correct biomarker and identification of optimal biomarker assays. Although there are many steps before a drug candidate reaches the market, accurate and early biomarker method validation enhances decision-making during every phase of drug development. NorthEast BioLab assists in establishing an early efficacy window for a potential drug candidate through robust biomarker development and validation services, thus eliminating the unavoidable, yet predictable, side-effects of a drug product.
Preclinical Study
Biomarker assay validation in preclinical pharmacokinetic and pharmacodynamic models validate the efficacy of the dose for clinical trials. Put differently, our scientists utilize biomarkers in animal studies to understand the duration and effect of exposure to a drug compound in animal studies. Additionally, biomarkers are used in preclinical models to evaluate the optimum dose for clinical trials. Preclinical biomarker assay testing
measures plasma concentration of the compound and corresponding target activity at the site of action.
Clinical Study
Biomarker assay services are critical during clinical trials. Initially, biomarkers are used to specify the inclusion criteria used for human volunteers. During clinical trials, biomarkers can be tracked to measure safety and efficacy, a critical process for drug approval. Biomarkers are also crucial in measuring disease progression during drug treatment. NorthEast BioLab conducts the assay development and validation to identify accurate biomarkers.
Biomarker discovery services ultimately help measure vital drug safety and efficacy data in clinical treatments accurately. There are genomic biomarkers for gene expression and specific gene sequences for disease identification, with treatment based on these biomarkers. Proteomic biomarkers include highly specific and sensitive protein biomarkers that help explain disease pathways, identify high-risk individuals for developing a disease, or explain therapeutic response towards intervention including any side effects. Cellular biomarkers utilize multiparameter analysis for differentiating large and rare sample cell types to provide meaningful information for supporting proteomic and genomic biomarker workflow.
Biomarker discovery is a multistep process that involves biomarker identification, qualification, assay development, validation, and clinical implementation. Biomarker qualification entails identifying biomarkers or biomarker assay, whereas assay development and validation establish fitness for use and implementation in the clinical setting. The outcome of a clinical trial using biomarkers as a surrogate endpoint requires high confidence biomarker study with valuable information on how crucial proteins behave during diseases. Comprehensive biomarker assay validation requires many patients to cover the broader spectrum of outcomes.
In modern medicine, biomarker development services are utilized as a drug approval tool and undergo thorough discovery, validation, and qualification steps. Biomarker development services could span multiple years throughout the drug development and clinical diagnostic use approval. Thus, biomarker development and validation services comprise of a challenging multistep process with only a ~10% estimated success rate of entering in phase I trial. Generally, the biomarker development success rate is affected by pharmacogenetic heterogeneity of patients to treatments and biologic response, the efficacy of administered drugs, and the lack of well-established biomarker assay services.
Biomarker Development has many phases –
Biomarker validation services involve establishing documented evidence of assurance that a specific biomarker will consistently produce an outcome in keeping with its predetermined specifications. Biomarker assay validation follows the “fit-for-purpose” (FFP) principle that includes the many distinct stages from a typical assay validation process. Biomarker assay development and validation are broadly categorized into analytical and clinical validations. Analytical validity signifies how well the biomarker quantitate what it is supposed to measure, ensuring sensitivity, specificity, accuracy, and precision, among other criteria. Clinical validity addresses how well the biomarker fulfills its purpose in predicting a clinically significant outcome, ensuring the diagnostic test or device performs as intended.
Biomarker qualification services entails the development and regulatory acceptance of biomarkers for use in drug development. The traditional route for biomarker acceptance by regulatory authorities is through data submission during a single drug program. In contrast, the Center for Drug Evaluation and Research (CDER) established a Biomarker Qualification Program (BQP) to review biomarkers for a specific context of use (COU) and release relevant information publicly. The qualified biomarker can then be used in multiple drug programs for this COU without re-review, accelerating the drug development paradigm. The US FDA maintains this list of qualified biomarkers to be used by drug developers without re-evaluating their validity. For additional context, biomarker discovery is the process of qualifying the biomarker, demonstrating biomarker assay for specific use in multiple drug programs without reconfirming the suitability, and verifying that the clinical biomarker testing is feasible and reliable. Qualified biomarkers must fulfill their stated context of use (COU).
Biomarker testing plays an essential role in drug development and help evaluate drug efficacy and safety in clinical trials to facilitate regulatory decision making. Examples of clinical biomarker services that we use in everyday life include tracking blood pressure or monitoring the blood glucose level. Biomarker testing services help evaluate molecular pathways leading to diseases, and biomarkers assay development helps in target identification and mechanism of action (MOA). In preclinical development, biomarker assay testing enables dose selection, MOA, and safety assessment. In the clinical phase, biomarker labs support dose selection, stratification, enrichment, as well as safety and efficacy examination. Generally, select biomarker assay development can identify drug efficacy much effectively than traditional clinical endpoints. That said, multiple data points needed to understand these biomarkers.
