Interleukin-21 (IL-21), produced predominantly by CD4 T cells and natural killer T (NKT) cells, is a newly discovered member of the common γ-chain family of cytokines. It has been implicated in many immunological processes and has been linked to autoimmune diseases, allergies and other inflammatory diseases. IL-21 Protein, Mouse, Recombinant (His & Avi), Biotinylated is expressed in E. coli expression system with N-His-Avi tag. The predicted molecular weight is 17.9 kDa and the accession number is Q9ES17.
