Detection of Mouse CD47 by Western Blot. Western blot shows lysates of mouse ovary tissue and mouse thymus tissue. PVDF membrane was probed with 0.25 µg/mL of Goat Anti-Mouse CD47 N-terminal IgV-like Extracellular Domain Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1866) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for CD47 at approximately 40-50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

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). 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).
