Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS, 5% trehalose and mannitol. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Human Signal regulatory protein alpha, Fc Chimera (HEK293-expressed) (rHuSignal regulatory protein α, Fc Chimera) to 100 μg/mL using ddH2O or diluted with PBS. Storage & Stability Lyophilized recombinant Human Signal regulatory protein alpha, Fc Chimera (HEK293-expressed) (rHuSignal regulatory protein α, Fc Chimera) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Signal regulatory protein α (SIRPα) is a glycoprotein receptor that recruits and signals via the tyrosine phosphatases SHP-1 and SHP-2.The cytoplasmic domain of SIRPα contains four immunoreceptor tyrosine-based inhibition motifs (ITIMs), which upon phosphorylation recruit and activate SH2-domain-containing phosphotyrosine phosphatases (PTPase) SHP-1 and SHP-2. In macrophages SIRPα can negatively regulate the phagocytosis of host cells and the production of tumor necrosis factor alpha. SIRPα ligation induces macrophage NO production through the cooperative action of JAK/STAT and PI3-K/Rac1/NOX/H2O2 signaling pathways. It proposes that SIRPα may function as an inhibitory receptor[1]. |
