anti-CD47 Purified (Preservative-free)

Human CD47 (IAP, Integrin Associated Protein) is a broadly expressed  Ig superfamily glycoprotein of about 50kD with a long extracellular Ig like domain, 5 transmembrane domains and an alternatively spliced intracellular c-terminal domain.  It interacts with it ligand SIRP alpha (CD172a, Signal Regulatory Protein) expressed mainly on myeloid cells serving as a negative immune regulator, inhibiting phagocytosis.  The CD47-SIRPa axis is being investigated as possible anti-tumor immune intervention point. Blockade of this interaction has shown promise in models of HNSCC(2), Glioma(3) and Breast Cancer(4)

Isotype:  Mouse IgG1k

Immunogen:  Recombinant human CD47 (extracellular Ig domain)

Specificity: Clone ANC2F6 binds to an epitope within the extracellular Ig-like domain of human CD47.
