蛋白结构(Molecular Characterization)

CD47 Structure

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 under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记(Labeling)

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白标记度(Protein Ratio)

Passed as determined by the HABA assay / binding ELISA.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

电泳(SDS-PAGE)

CD47 SDS-PAGE

Biotinylated Human CD47, His,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.

 

活性(Bioactivity)-ELISA

CD47 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

CD47 ELISA

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

 

活性(Bioactivity)-FACS

CD47 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

CD47 FACS

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

Protocol

 

背景(Background)

Leukocyte surface antigen CD47 is also known as Antigenic surface determinant protein OA3, Integrin-associated protein (IAP) and Protein MER6. CD47 contains 1 Ig-like V-type (immunoglobulin-like) domain. CD47 is very broadly distributed on normal adult tissues. CD47 has a role in both cell adhesion by acting as an adhesion receptor for THBS1 on platelets, and in the modulation of integrins and plays an important role in memory formation and synaptic plasticity in the hippocampus by similarity. CD47 is the receptor for SIRPA, binding to which prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. CD47 Interaction with SIRPG mediates cell-cell adhesion, enhances superantigen-dependent T-cell-mediated proliferation and costimulates T-cell activation.
