(Synonyms: Za11, Interleukin-21, IL-21, CVID11) Copy Product InfoSynonyms: Za11, Interleukin-21, IL-21, CVID11
Catalog No. TMPK-00043 Copy Product Info
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, Human, Recombinant (His & Avi), Biotinylated is expressed in E. coli expression system with N-His-Avi tag. The predicted molecular weight is 18.30 kDa and the accession number is Q9HBE4-1.
