CD55 (DAF) antibodies, mouse

Clone: REA300 | Dilution: 1:10
Clone REA300 recognizes the CD55 antigen, a glycoprotein also known as complement decay-accelerating factor (DAF). There are two mouse CD55 genes, which share 85% nucleotide and 78% amino acid identities, and have been designated CD55-glycosylphosphatidylinositol and CD55-transmembrane to reflect the two alternate mechanisms of membrane attachment. Both proteins are recognized by clone REA300. CD55 is broadly distributed among hematopoietic and non-hematopoietic cells. It is expressed on the plasma membranes of all cell types that are in intimate contact with serum and it is also found on the surfaces of epithelial cells, lining extracellular compartments. CD55 plays multiple physiologic roles including tissue protection from the cytotoxic complement injury, anti-inflammatory function owing to its anti-adherence properties which enhance transmigration of monocytes and macrophages and reduce tissue injury. CD55 plays an essential role during pregnancy and is involved in the protection of the semiallogeneic fetus and in preventing uncontrolled infiltration by white cells. It is exploited in multiple pathologic conditions by pathogens and viruses in chronic tissue infection processes.
Additional information: Clone REA300 displays negligible binding to Fc receptors.
