Acitve Recombinant Mouse SIRPA protein(Met1-Asn373), His-tagged

• Cat.No.: SIRPA-1251M
• Product Overview: Recombinant Mouse SIRPA (BAA20376.1) (Met1-Asn373) was expressed in HEK293 with a C-terminal polyhistidine tag.

Specification

• Species: Mouse
• Source: HEK293
• Tag: His
• Protein Length: Met1-Asn373
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Measured by its binding ability in a functional ELISA. Immobilized Mouse SIRPA-His at 10 μg/ml (100 μl/well) can bind Human CD47-Fc, The EC50 of Human CD47-Fc is 0.05-0.13 μg/ml.
• Molecular Mass: The secreted recombinant Mouse SIRPA comprises 353 amino acids and has a calculated molecular mass of 39.4 kDa. As a result of glycosylation, the apparent molecular mass of Mouse SIRPA is approximately 50-70 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 95 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
