| Interleukin-21 (IL-21), produced predominantly by CD4 T cells and natural killer T (NKT) cells, is a newly discovered member of the common ?-chain family of cytokines. It has been implicated in many immunological processes and has been linked to autoimmune diseases, allergies and other inflammatory diseases. |
| Recombinant Human IL-21 Protein is expressed from E.coli without tag. It contains Gln32-Ser162. |
