This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag (Avitag™).
The protein has a calculated MW of 65.8 kDa. The protein migrates as 75-105 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Biotinylated Human SIRP alpha, Fc,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
The purity of Biotinylated Human SIRP alpha, Fc,Avitag(Cat. No. CDA-H82F2) was more than 90% and the molecular weight of this protein is around 155-170 kDa verified by SEC-MALS.
FACS assay shows that Biotinylated Human SIRP alpha, Fc,Avitag (Cat. No. CDA-H82F2) can bind to Jurkat cell expressing CD47. The concentration of SIRP alpha used is 3 μg/mL (QC tested).
FACS analysis shows that the binding of Biotinylated Human SIRP alpha, Fc,Avitag (Cat. No. CDA-H82F2) to Jurkat expressing CD47 was inhibited by increasing concentration of neutralizing Anti- Human CD47 antibody. The concentration of SIRP alpha used is 1 μg/mL. IC50=0.1303 μg/mL (Routinely tested).
