Background Information

The first component of complement is a calcium-dependent complex of the 3 subcomponents C1q, C1r, and C1s. The serine protease subunits C1r and C1s form a Ca(2+)-dependent C1s-C1r-C1r-C1s tetramer. C1r acts by transforming the activation signal into an enzymic activity. C1r is a single-chain glycoprotein that can be cleaved into an A chain and a B chain upon activation. This antibody recognizes the full-length C1r chain and the cleaved B chain.
