Recombinant Human IL21R Protein, C-His-tagged

Specification :
| Description : The IL-21 receptor (also designated IL-21R, NILR or novel interleukin receptor) is a type I cytokine receptor that forms a complex with the cytokine receptor γ chain, γc and mediates IL-21 signaling. IL-21R is present on the surface of natural killer, B and T cell populations with high levels in spleen and thymus. IL-21 and IL-21R influence lymphoid proliferation and early lymphoid development in the transition between innate and adaptive immunity. Tumor necrosis factor (TNF) upregulates IL-21R, and combinations of TNF and IL-21 can have synergistic effects on myeloma cell proliferation through pathways involving phosphorylation of JAK1, Stat3 and Erk1/2. The human IL-21R gene maps to chromosome 16p12.1 and encodes a 538 amino acid protein that is closely related to human IL2RB and shares 62% sequence identity to mouse Il21r. | Source : E. coli | Species : Human | Tag : C-His | Molecular Mass : ~23 kDa | AA Sequence : CPDLVCYTDYLQTVICILEMWNLHP STLTLTWQDQYEELKDEATSCSLHR SAHNATHATYTCHMDVFHFMADDIF SVNITDQSGNYSQECGSFLLAESIK PAPPFNVTVTFSGQYNISWRSDYED PAFYMLKGKLQYELQYRNRGDPWAV SPRRKLISVDSRSVSLLPLEFRKDS SYELQVRAGPMPGSSYQGTWSEWSD PVIFQTQSEELKE | Purity : Transferred into competent cells and the supernatant was purified by NI column affinity chromatography and the purity is > 85% (by SDS-PAGE). | Notes : For research use only, not for use in diagnostic procedure. | Storage : Store at 4 centigrade short term.
