This antibody binds the extracellular domain of the human CD47, which is broadly distributed on normal adult tissues, as well as ovarian tumors, and is especially abundant in some epithelia and the brain. IAP or integrin assocaited protein has a role in b

This antibody displayed high specificity and affinity for CD47 protein, which were comparable to those for humanized anti-CD47 blocking antibody B6H12. This antibody is could efficiently block the physical interaction of immobilized recombinant human CD47 to human and mouse SIRPalpha in blocking assay in vitro and was capable of inducing in vitro macrophage-mediated phagocytosis as robust as B6H12. It binds recombinant human CD47 in a dose dependent manner in an ELISA. This antibody was also capable of recognizing cell-surface expressed CD47 in a flow cytometry. The binding affinity of the IgG version of this antibody toward CD47 was determined to be 3.50 +/- 0.16 nM using surface plasmon resonance. ZF1 treatment could induce robust phagocytosis of leukemic cancer cells by macrophage in vitro, and protect BALB/c nude mice from cancer killing by engrafted leukemic cells (CCRF and U937) to a similar extent as humanized B6H12 did (PMID: 27863402).

Leukocyte surface antigen CD47

This chimeric rabbit antibody was made using the variable domain sequences of the original Human IgG1 format for improved compatibility with existing reagents assays and techniques.

The original antibody was isolated after screening of three lambda3-H3, lambda3-H5 and lambda1-H3 phage display single-chain variable fragments (scFvs) libraries by panning against recombinant protein antigen CD47-His. The variable domain genes of the antibody were cloned into a pair of eukaryotic cell expression vectors and co-transfected into FreeStyle HEK293T cells for expression and obtaining the IgG antibody.
