Other Tags and Version Biotin & Other Labeled Version
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 16.9 kDa. The protein migrates as 32-44 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Labeling
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
Protein Ratio
Passed as determined by the HABA assay / binding ELISA.
Purity
>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.

Report
Bioactivity-ELISA
Immobilized Monoclonal Anti-Human CD47 Antibody, Human IgG4 at 2 μg/mL (100 μL/well) can bind Biotinylated Human CD47, His,Avitag (Cat. No. CD7-H82E9) with a linear range of 0.1-3 ng/mL (QC tested).
Protocol
Immobilized Human SIRP alpha, Fc Tag (Cat. No. SIA-H5251) at 2 μg/mL (100 μL/well) can bind Biotinylated Human CD47, His,Avitag (Cat. No. CD7-H82E9) with a linear range of 2-25 ng/mL (Routinely tested).
Protocol
Bioactivity-FACS
FACS assay shows that Biotinylated Human CD47, His,Avitag (Cat. No. CD7-H82E9) can bind to ACHN cell expressing human SIRP-a. The concentration of CD47 used is 10 μg/mL (Routinely tested).
Protocol
FACS analysis shows that the binding of Human CD47 to ACHN expressing SIRP-a was inhibited by increasing concentration of neutralizing SIRP-a antibody. The concentration of Human CD47 used is 20 μg/mL. IC50=9.334 μg/mL
