Anti-Rat DAF Monoclonal Antibody (clone RDII-24) -0.5 mg (CAT#: CB-P305-AB) Datasheet

Antibody

The monoclonal antibody RDII-24 recognizes complement decay accelerating factor (DAF), also known as CD55. Cells express several proteins on their surface that protect against complement attack, namely C receptor I (CR1), decay accelerating factor (DAF) , Membrane Cofactor Protein (MCP) and CD59. CR1, DAF and MCP regulate the activation pathway of complement by accelerating the decay of C3 and C5 convertase (CR1, DAF) or acting as a cofactor for serine protease I. The cleavage of this factor is irreversible Ground inactivation of C3b (CR1, MCP).
Rat DAF (CD55) is a 60 kDa transmembrane protein that binds to C3b and C4b and can inhibit the formation and half-life of C3 convertase. It belongs to the complement activation (RCA) family of receptors. DAF is widely distributed in cells in contact with plasma complement proteins, including hematopoietic and non-hematopoietic cells. Although DAF has no important role in controlling hemolysis of red blood cells, it plays an important role in regulating the deposition of C3 on nucleated cells.
DAF works with other complement regulators to protect one's own cells from damage mediated by autologous complement. DAF and CD46 work together to avoid the deposition of autologous C3, while CD59 inhibits this pathway at a key endpoint.
