Used in immunological research to quantify levels of MIP-3β (CCL19), a chemokine involved in lymphocyte trafficking and dendritic cell recruitment. The ELISA kit enables accurate measurement of CCL19 in biological samples such as serum, plasma, and cell culture supernatants. It is widely applied in studies related to autoimmune diseases, inflammation, cancer immunology, and vaccine development. Researchers use it to assess immune responses, monitor disease progression, and evaluate therapeutic interventions targeting chemokine pathways. The assay provides high sensitivity and specificity, making it suitable for both basic research and preclinical studies.
