Target/Specificity Mouse anti-Human C4d antibody, clone 10-11 recognizes the secreted protein complement component 4d (C4d). The presence of C4d in renal peritubular capillaries is a key indicator for acute antibody-mediated rejection [AMR] (Collinset al.1999.).C4d was accepted in 2003 into the Banff classification for identification of acute AMR (Racusenet al.2003). Mouse anti-Human C4d antibody, clone 10-11 is specific for C4d, a marker that can be used in the detection of acute AMR for kidney, heart, pancreas and lung allografts. C4d is regarded as a key marker of antibody-mediated cell injury and humoral rejection (Sacks and Chowdhury 2002).Complement 1 complex cleaves complement 4 (C4) to form C4b and C4a. C4b levels are strictly regulated. Single site cleavage of the C4b’s alpha chain by Factor I forms iC4b and blocks C3 convertase, inhibiting opsonization and activation of the classical pathway. This requires C4 binding protein or CR1 as a cofactor. iC4b is further degraded into C4d and C4c. C4b’s short half life means that C4d is present in serum at high enough concentrations to make it a useful marker for classical complement activation (Collinset al.1999).Mouse anti-Human C4d antibody, clone 10-11 is used to detect the biomarker C4d which has been described as a “footprint” of antibody mediated tissue rejection (Sacks and Chowdhury 2002). The internal thioester of C4b becomes exposed during cleavage to C4d and forms a covalent bond with the cell surface. The longer half-life of covalently bound C4d makes it a footprint of complement activation long after weakly bound antibodies have been cleared by the blood stream (Sacks and Chowdhury 2002).C4 has also been linked to susceptibility to systemic lupus erythematosus (Yanget al.2004) and rheumatoid arthritis (Makindeet al.1989).
