SIRP alpha (Signal regulatory protein alpha; also SHPS1 and BIT) is a variably glycosylated 90-120 kDa member of the SIRP family of proteins. It is widely expressed, being found on neurons, microglia/macrophages, endothelium, and fibroblasts. SIRP alpha has a variety of functions, including presynsptic organization, inhibition of integrin action, and induction of myogenesis. It binds to CD47 and likely other ligands. Mature human SIRP alpha is a 477 amino acid (aa) type I transmembrane glycoprotein. It contains an extracellular region (aa 27-372) that shows one V-type Ig-like (aa 32-137) and two C2-type Ig-like domains (aa 147-347). Its cytoplasmic domain possesses two ITIMs which interact with protein tyrosine phosphatases. There is one alternative start site at Met102 plus a four aa insertion after Gln421. Over aa 27-370, human SIRP alpha shares 61% aa identity with mouse SIRP alpha.

Human SIRP alpha /CD172a ELISA Standard Curve.
Recombinant Human SIRP alpha /CD172a protein was serially diluted 2-fold and captured by Mouse Anti-Human SIRP alpha /CD172a Monoclonal Antibody (Catalog # MAB45462) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human SIRP alpha /CD172a Monoclonal Antibody (Catalog # MAB45461) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).Applications for Human SIRP alpha/CD172a Antibody (602407)
