CD55, CD55 antigen, Decay-accelerating factor, TC, CR, CROM, DAF
(tested or 100% immunogen sequence identity)
CD55 antibody was raised against human fibroblast cell line
Recognizes the CD55 antigen, a 70kD glycoprotein also known as Decay Accelerating Factor (DAF). This antibody has a functional binding affinity to erythrocytes of 8.7x10^7 M-1. The antigen is pronase and trypsin resistant and chymotrypsin sensitive. 3H1564 recognizes the consensus region 3 of the DAF molecule, which contains the functional site and the antibody blocks the function of DAF.
