Description
Introduction: Interleukin-21 receptor, also known as IL21R is a member of the type I cytokine receptors family. IL21R forms a heterodimeric receptor complex with the common gamma-chain, a receptor subunit which is also shared by the receptors for interleukin 2, 4, 7, 9, and 15. Furthermore, IL21 receptor transduces the growth promoting signal of IL21, and is significant for the proliferation as well as differentiation of T cells, B cells, and natural killer (NK) cells. The ligand binding of IL21 receptor leads to the activation of numerous downstream signaling molecules, including JAK1, JAK3, STAT1, as well as STAT3.
Description: IL21R produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain (20-232 a.a.) and fused to an 8 aa His Tag at C-terminus containing a total of 221 amino acids and having a molecular mass of 25.6kDa.IL21R shows multiple bands between 28-40kDa on SDS-PAGE, reducing conditions and purified by proprietary chromatographic techniques
