C4b antibody

WebProduct Description. C4b is derived from native C4 upon cleavage and release of C4a. It is prepared by cleavage of purified C4 with the classical pathway activated protease C1s enzyme (#A104). Native human C4b is a glycosylated (~7.3%) polypeptide containing three disulfide-linked chains. C4b is central to the function of two of the three ... WebFurther cleavage of the C4b alpha chain by Factor I forms C4d and C4c, where C4d remains bound close to the site of C4b binding. The longer half-life of covalently bound C4d versus C4b makes it a perfect marker of complement activation long after weakly bound antibodies have been cleared by the blood stream (Sacks and Chowdhury 2002).
