Cytokines are signaling proteins secreted by immune cells. The primary function of cytokines is to coordinate cell growth, proliferation, and differentiation. Cytokines have numerous functions, including inflammation, angiogenesis, tumorigenesis, immune cell differentiation, innate and adaptive immunity, immunobiology, and pathogenesis. Today it is well known that dysregulation of cytokine expression is the underlying cause of numerous inflammatory and immunological diseases.
Meso Scale Discovery multiplex assays have emerged as a promising tool for cytokine analysis and immunogenicity testing. With options such as MSD cytokine assay and NAb assay development, MSD multiplex ELISA assays are advancing immunogenicity testing in numerous ways. Let us dive deep and understand this cutting-edge technology.
Advances in immunogenicity testing
Intracellular signaling is a vital field in biology research. Extracellular data should be accurately translated into intracellular responses. These complex signaling cascades are crucial for regulation, proliferation, secretion, and apoptosis. MSD offers bioanalytical assays to support intracellular signaling research. These multiplex and singleplex assays can measure phosphoproteins and ubiquitinated proteins to evaluate intracellular signaling cascades.
Immunogenicity testing is crucial for biopharmaceutical drug development. The US FDA has strict regulatory requirements for developing and validating ADA assays. Such stringent recommendations require more tolerant and robust methods. Over time, Meso Scale Discovery multiplex assays have emerged as a promising tool for assessing anti-drug antibodies during immunogenicity testing. MSD assays have a broader dynamic range, enhanced therapeutic tolerance, and increased sensitivity.
