Description
Human IL21 Recombinant Protein (C-His)
Human IL21 Recombinant Protein (C-His) is a recombinant protein expressed in E. coli, spanning Leu23-Ser162, with a C-terminal His tag. Predicted molecular weight: 17.45 kDa. Purity: >90% as determined by SDS-PAGE. Supplied lyophilized from a solution in PBS pH 7.4, 0.02% NLS, 1 mM EDTA, 4% Trehalose, 1% Mannitol. Applications: ELISA, immunogen, SDS-PAGE and Western blot. Interleukin-21 (IL21) is a ~18 kDa protein. Cytokine with immunoregulatory activity. For research use only.
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.
