Specificity
This antibody recognises bovine interleukin-21 (IL-21), a 16.95 kDa cytokine belonging to the IL-15/IL-21 family. IL-21 is a cytokine with immunoregulatory activity. IL-21 stimulates B- and T-cell proliferation and increases the activity of NK cells and disease-specific cytotoxic T-cells. Interleukin-21 is believed to inhibit dendritic cell activation and maturation during the T-cell mediated immune response.
