    • Rabbit anti Human interleukin-21 antibody recognizes human Interleukin-21 (IL-21), also known as Za11. 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. It might also inhibit dendritic cell activation and maturation during the T-cell mediated immune response.
