||IFN-γ receptor ligand-binding chain (IFNγR1) or IFN-γ R α chain, also known CDw119, is member of the class II cytokine receptor family. The IFN-γ receptor is a complex of a high affinity IFN-γ-binding chain (aka, IFN-γ R α chain) and a second accessory protein required for signal transduction known as IFN-γ R β chain. Binding of IFN-γ induces receptor dimerization and internalization. Signal transduction involves Jak1 and Jak2 protein kinases and involves STAT1 activation. The IFN-γ receptor is expressed at moderate levels on virtually every cell with the exception of erythrocytes.
||The predicted molecular weight of Recombinant Human IFN-γ R1 is Mr 25 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 40-50 kDa.
|State Of Matter:
||> 95% by SDS Page and analyzed by silver stain.
||< 1.0 EU/µg as determined by the LAL method.
|Storage And Stability:
||This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.
