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.

Source
MABSol® Biotinylated Human CD47, Fc,Avitag (CD7-H82F6) is expressed from human HEK293 cells. It contains AA Gln 19 - Pro 139 (Accession # NP_942088).
Predicted N-terminus: Gln 19

Molecular Characterization
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 42.2 kDa. The protein migrates as 50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

Biotin:Protein Ratio
The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

Endotoxin
Less than 1.0 EU per μg by the LAL method.

Purity
>95% as determined by SDS-PAGE.

Formulation
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Reconstitution
Reconstitute at 100 μg/mL in sterile deionized water. For best performance,we strongly recommend you to follow the reconstitution protocol provided in the COA.

Storage
For long term storage, the product should be stored at lyophilized state at -20° C or lower. Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at: 4-8° C for 12 months in lyophilized state; -70° C for 3 months under sterile conditions after reconstitution.
 

Bioactivity
