Assay Services

Soluble proteins including cytokines, chemokines and growth factors are small proteins that mediate and regulate immunity, and are involved in many diseases including cancers. The concentration of these proteins in blood and tissues may help to understand inflammatory response pathways or disease progression. Consequently, cytokines are very useful as a tool for screening, diagnosis classification between stages of disease or surveillance for therapy.

At Precision, we develop and customize assays to detect specific groups of cytokines of interest, using the most appropriate approach-including ELISA, Luminex, MesoScale, and Quanterix SIMOA.

Sensitivity and multiplex capabilities of Precision’s cytokine profiling platforms

Precision’s technologies providing biomarker
and safety insights


ELISA is a well-recognized and understood tool for quantitative, antibody-based analysis. Precision’s ELISA services include assay development or transfer, validation, and implementation.


Luminex is useful when multiplexed measurements at high sensitivity, even in complex matrices, are needed. We generally utilize the Luminex platform in early phase studies profiling cytokines and other analytes.

Quanterix SIMOA®

Quanterix SIMOA provides precise quantification of analytes in multiple matrices at ultra-high sensitivity. This platform can measure targets present at femtomolar (fM) levels, enabling analysis of analytes that may have been previously undetectable.

MesoScale Discovery (MSD) Assays

MSD assays provide multiplexed measurements of up to 10 analytes in complex sample matrices consistently and at high sensitivity. Suitable for all phases of development, applications include cytokine profiling, immunogenicity testing, and more.

Automated Western Blotting (Immunoblotting)

Western blotting, also known as immunoblotting, is commonly used for validating the presence and expression of specific proteins that may serve as targets or biomarkers in research or diagnostic applications.

Olink Proteomics

Olink’s protein biomarker platform allows for the high-multiplex quantification of protein biomarkers with minimal clinical sample volume and exceptional sensitivity and specificity, enabling in-depth disease modeling, longitudinal studies and translational research.
