Recombinant Human PSAP protein, His-tagged

• Cat.No.: PSAP-20H
• Product Overview: Recombinant Human PSAP(Met1-Asn524) fused with His tag at C-terminal was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 1-524 a.a.
• Description: This gene encodes a highly conserved glycoprotein which is a precursor for 4 cleavage products: saposins A, B, C, and D. Each domain of the precursor protein is approximately 80 amino acid 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. Mutations in this gene have been associated with Gaucher disease, Tay-Sachs disease, and metachromatic leukodystrophy. Alternative splicing results in multiple transcript variants encoding different isoforms.
• Predicted N Terminal: Gly
• Form: Lyophilized from sterile PBS, pH 7.4.
• Molecular Mass: The recombinant human PSAP consists 519 amino acids and predicts a molecular mass of 57.9 kDa.
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: > (79.8+19.7) % as determined by SDS-PAGE.
• Stability: Samples are stable for up to twelve months from date of receipt at -70 centigrade
• Storage: Store it under sterile conditions at -20 centigrade to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
