C4b antibody
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). WebSep 15, 2024 · The classical and lectin pathways of the complement system are important for the elimination of pathogens and apoptotic cells and stimulation of the adaptive immune system. Upon activation of these pathways, complement component C4 is proteolytically cleaved, and the major product C4b is deposited o …
