LEGEND MAX™ Human IL-4 ELISA Kit

Human IL-4 (Interleukin-4, Ia inducing factor (IaIF), B-cell stimulating factor-1,BSF-1, Hodgkin’s cell growth factor, HCGF, Mast cell growth factor-2, MCGF-2, Macrophage fusion factor, MFF, T cell growth factor-2, TCGF-2) is a pleiotropic cytokine that is produced by activated T cells, mast cells and basophils. IL-4 elicits many different biological responses, but has two dominant functions. IL-4 regulates differentiation of naïve CD4+ T cell to Th2 cells. Th2 cells produce IL-4, IL-5, IL-10 and IL-13, which tend to favor a humoral immune response while suppressing a cell-mediated immune response controlled by Th1 cells. In addition, IL-4 regulates IgE and IgG1 production by B cells.

BioLegend’s LEGEND MAX™ Human IL-4 ELISA Kit is a sandwich Enzyme-Linked Immunosorbent Assay (ELISA), in which, a Human IL-4 specific monoclonal antibody is pre-coated on a 96-well strip-well plate.

BioLegend’s LEGEND MAX™ Human IL-4 ELISA Kit is specifically designed for the accurate quantitation of Human IL-4 from cell culture supernatant, serum, plasma or other bodily fluids. It is ready-to-use, accurate, and sensitive.
