IL-9 is a T cell growth factor predominately produced by antigen stimulated CD4+ T helper cells. It acts as a regulator of hematopoietic cells, stimulates proliferation, and protects T cells from apoptosis induced by IL-2 withdrawal. IL-9 enhances mast cell activity and IL-3- or IL-4- dependent proliferation of bone marrow-derived mast cells. IL-9 synergizes with erythropoietin to promote erythroid colony formation. IL-9 is upregulated in human eosinophils by TNF-α and IL-1β, indicating its role in asthma and allergic diseases.
The BioLegend LEGEND MAX™ Human IL-9 ELISA Kit is a Sandwich EnzymeLinked Immunosorbent Assay (ELISA) with a 96-well strip plate that is precoated with a capture antibody. This kit is specifically designed for the accurate quantitation of human IL-9 from cell culture supernatant, serum, plasma, and other biological fluids. This kit is analytically validated with ready-to-use reagents.
