Detection of CD47 antibody in HEK293 Human Cell Line Transfected with Mouse CD47 and eGFP antibody by Flow Cytometry.

Detection of CD47 in HEK293 Human Cell Line Transfected with Mouse CD47 and eGFP by Flow Cytometry.

HEK293 human embryonic kidney cell line transfected with either (A) mouse CD47 or (B) irrelevant protein, and eGFP was stained with Rat Anti-Mouse CD47 Monoclonal Antibody (Catalog # MAB18661) followed by Allophycocyanin-conjugated Anti-Rat IgG Secondary Antibody (Catalog # F0113). Quadrant markers were set based on isotype control antibody (Catalog # MAB005, data not shown). View our protocol for Staining Membrane-associated Proteins.

CD47 Binding to SIRP alpha /CD172a Blocked By Mouse CD47 Antibody.

CD47 Binding to SIRP alpha /CD172a Blocked By Mouse CD47 Antibody.

In a functional ELISA, 0.08-0.8 µg/mL of this antibody (green line) will block 50% of the binding of 0.25 µg/mL of Recombinant Mouse CD47 Fc Chimera (orange line, Catalog # 1866-CD) to immobilized Recombinant Mouse SIRPa/CD172a Fc Chimera (Catalog # 7154-SA) coated at 1 µg/mL (100 µL/well). At 5 µg/mL, this antibody will block >90% of the binding.

Background: CD47

CD47, also known as Integrin‑Associated Protein (IAP) and OA3, is a 40‑60 kDa variably glycosylated atypical member of the immunoglobulin superfamily (1, 2). Mouse CD47 is an integral membrane protein that consists of a 122 amino acid (aa) extracellular domain (ECD) with a single Ig‑like domain, five membrane-spanning regions with short intervening loops, and a 16 aa C‑terminal cytoplasmic tail (3). Alternate splicing of mouse CD47 generates an additional isoform with an insertion of 21 aa following the Ig‑like domain (3). Within the N‑terminal ECD, mouse CD47 shares 63% and 84% aa sequence identity with human and rat CD47, respectively. A portion of the N‑terminal ECD can by shed from smooth muscle cells by MMP-2‑mediated proteolysis (4). The ubiquitously expressed CD47 binds to SIRP family members on macrophages, neutrophils, and T cells (5, 6). These interactions prevent macrophage‑mediated clearance of healthy CD47-expressing cells and promote immune cell transmigration across the vascular endothelium (5‑8). The CD47-SIRP alpha interaction is species specific, and this lack of cross-species interaction has been implicated in xenotransplantation rejection (16). CD47 associates in cis with Fas on T cells and enhances Fas‑mediated apoptosis; its ligation promotes T cell anergy and dampens Th1 immune responses (9‑11). CD47 also associates in cis with Integrins alpha 4 beta 1, alpha V beta 3, alpha 2b beta 3, and alpha 2 beta 1 which can positively or negatively modulate Integrin-mediated function (2, 12). In the vasculature, CD47 binding by Thrombospondin‑1 inhibits the angiogenic and vasorelaxant effects of nitric oxide (2, 13, 14). On dendritic cells and myeloma cells, CD47 ligation by TSP‑1 induces giant cell formation and osteoclast differentiation (15).
