Description
Description: The monoclonal antibody eBio2B2-G20 reacts with human IL-21, a potent stimulator of NK and cytolytic T cells. IL-21 is a 131 amino acid protein most closely related to IL-2 and IL-15. Expression is found in CD4+ cells upon activation. In addition to its effect on NK cells, IL-21 stimulates proliferation of B-cell stimulated by crosslinking of the CD40 antigen and stimulates the proliferation of bone marrow progenitor cells and the expression of the NK-cell marker CD56 in the presence of IL-15. Applications Reported: The eBio2B2-G20 antibody has been reported for use in ELISA detection of IL-21 analysis. Applications Tested: The eBio2B2-G20 antibody has been tested as the detection antibody in a sandwich ELISA for analysis of human Interleukin-21 (IL-21) in combination with the purified eBio3A3-N2 (Product # 14-7219-82) antibody for capture and recombinant human IL-21 (Product # 14-8219) as the standard. A suitable range of concentrations of this antibody for ELISA capture is 0.5-2 µg/mL. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 4000 pg/mL - 60 pg/mL should be included in each ELISA plate. Filtration: 0.2 µm post-manufacturing filtered.
