Anti-Interleukin-21 (IL-21) (chicken)

The Chicken IL-21 polyclonal antibody is unlabeled and has been qualified for use in ELISA and Western blot applications. It is the capture antibody in the Kingfisher Biotech Chicken IL-21 ELISA. The Chicken IL-21 polyclonal antibody was produced in goats and is antigen-affinity purified. The reactivity by species is: (Bovine IL-21 - None) (Canine IL-21 - None) (Chicken IL-21 - Strong). For research use only. Made in the USA Protein function: Cytokine with immunoregulatory activity. May promote the transition between innate and adaptive immunity. Induces the production of IgG(1) and IgG(3) in B-cells. Implicated in the generation and maintenance of T follicular helper (Tfh) cells and the formation of germinal-centers. Together with IL6, control the early generation of Tfh cells and are critical for an effective antibody response to acute viral infection. May play a role in proliferation and maturation of natural killer (NK) cells in synergy with IL15. May regulate proliferation of mature B- and T-cells in response to activating stimuli. In synergy with IL15 and IL18 stimulates interferon gamma production in T-cells and NK cells. During T-cell mediated immune response may inhibit dendritic cells (DC) activation and maturation.
