Invitrogen IL-21 Monoclonal Antibody (eBio3A3-N2 (3A3-N2)), eFluor™ 660, 100 Tests, eBioscience™

The monoclonal antibody eBio3A3-N2 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.

Staining for IL-21 has shown donor variability. stimulation times may vary depending on the donor and should be optimized. Increased staining levels have been observed on Th17-polarized normal human peripheral blood cells.
