Used in biomedical research to quantify Interleukin-19 (IL-19) levels in biological samples such as serum, plasma, and cell culture supernatants. This kit is particularly valuable in studies related to inflammatory diseases, autoimmune conditions, and immune response regulation. Researchers use it to investigate the role of IL-19 in conditions like asthma, psoriasis, and atherosclerosis, where cytokine activity influences disease progression. The assay enables high-throughput, accurate measurement of IL-19, supporting both clinical research and drug development efforts targeting the IL-10 cytokine family pathway.
