Recombinant protein corresponding to Gly17-Asn524 of human PSAP, expressed in E. coli.
Prosaposin also known as PSAP is a highly conserved glycoprotein which is a precursor for 4 cleavage products: saposins A, B, C, and D. Saposin is an acronym for Sphingolipid Activator PrO[S]teINs. Each domain of the precursor protein is approximately 80aa residues long with nearly identical placement of cysteine residues and glycosylation sites. Saposins A-D localize primarily to the lysosomal compartment where they facilitate the catabolism of glycosphingolipids with short oligosaccharide groups. The precursor protein exists both as a secretory protein and as an integral membrane protein and has neurotrophic activities. Saposins A-D are required for the hydrolysis of certain shingolipids by specific lysosomal hydrolases. Applications: Suitable for use in ELISA, Western Blot, Immunohistochemistry and Immunocytochemistry. Other applications not tested. Recommended Dilutions: Western Blot: 0.5-2ug/ml Immunohistochemistry (Paraffin): 5-20ug/ml Immunocytochemistry: 5-20ug/ml Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
