This item recognises the CD55 antigen, a 70kD glycoprotein also known as Decay Accelerating Factor (DAF). Distributed on erythrocytes and other circulating blood cells and also on cells in non-haemopoietic tissue particularly epithelium and endothelium. Found specifically at the foetal-maternal interfaces in placenta.CD55 has reduced expression on individuals with paroxysmal nocturnal haemoglobinuria. This antibody has a functional binding affinity to erythrocytes of 8.7 x 107 M-1. The antigen is pronase and trypsin resistant and chymotrypsin sensitive. BRIC 216 recognises the consensus region 3 of the DAF molecule, which contains the functional site, and the antibody blocks the function of DAF.
