Used for the quantitative detection of Interleukin 28A (IL-28A) levels in biological samples such as serum, plasma, or cell culture supernatants. This research kit is primarily employed in immunology and virology studies to investigate the role of IL-28A, a type III interferon, in antiviral responses, inflammation, and immune regulation. It enables researchers to monitor cytokine expression in experimental models of viral infection, autoimmune diseases, and therapeutic interventions. The assay supports high sensitivity and specificity, making it suitable for measuring low concentrations of IL-28A in small sample volumes. Widely used in preclinical research to evaluate immune responses and support biomarker discovery.
