Product Description	Recombinant Biotinylated Mouse IL-21 Protein is expressed from E.coli with His tag and Avi tag at the N-Terminus.It contains His18-Ser146.
Product Background	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.
