Used in immunological research to quantify levels of CXCL13, a chemokine involved in B-cell trafficking and lymphoid tissue formation. This ELISA kit enables detection of CXCL13 in biological samples such as serum, plasma, and cell culture supernatants. It is widely applied in studies related to autoimmune diseases like multiple sclerosis and rheumatoid arthritis, where CXCL17 elevation correlates with disease activity. Also used in cancer research, particularly in B-cell lymphomas and chronic inflammation, to understand immune cell recruitment and tumor microenvironment dynamics. Provides a reliable, sensitive, and specific method for monitoring CXCL13 expression in experimental and clinical settings.
