||Single immunoglobulin and toll-interleukin 1 receptor (TIR) domain, also known as SIGIRR is a member of the IL-1 receptor family. It acts as a negative regulator of interleukin (IL)-1 and lipopolysaccharide (LPS) signaling. It also plays a critical role in gut homeostasis, intestinal inflammation, and colitis-associated tumorigenesis by maintaining the microbial tolerance of the colonic epithelium.
||The predicted molecular weight of Recombinant Human SIGIRR is Mr 39 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 55-60 kDa.
|State Of Matter:
||>90% by SDS Page and analyzed by silver stain.
||<0.1 ng per 1 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℃ to -70℃. After aseptic reconstitution, this protein may be stored at 2℃ to 8℃ for one month or at -20℃ to -70℃ in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
