Bioactivity
1.Measured by its binding ability in a functional ELISA. Immobilized rat CD47-His (Cat:80305-R08H) at 10 μg/ml (100 μl/well) can bind mouse SIRPA-Fc, The EC50 of mouse SIRPA-Fc is 0.6-1.4 μg/ml. 2.Recombinant Mouse SIRP alpha/SHPS-1 Protein, hFc Tag (Cat. No. 50956-M02H) captured on Protein A chip can bind Recombinant Mouse CD47 Protein, His Tag (Cat. No. 57231-M08H) with an affinity constant of 0.5703 μM as determined in an SPR assay (Biacore T200) (Routinely tested) .
Function
Met1-Asn373
Molecular Weight
The secreted recombinant mouse SIRPA/Fc is a disulfide-linked homodimer. The reduced monomer comprises 583 amino acids and has a calculated molecular mass of 64.9 kDa. As a result of glycosylation, the apparent molecular mass of rmSIRPA/Fc monomer is approximately 1001-20 kDa in SDS-PAGE under reducing conditions.
