C4d Information for Pathologists
Summary:
C4d is a component of the classical and lectin complement cascade. C4d is a cleavage product of C4 which is first cleaved into C4a and C4b which is furter processed to C4c and C4d. C4d binds close to C4d and its presence is stable making it a good biomarker for complement activation.Common Uses By Pathologists:
C4d has been classically used to identify sites of tissue injury mediated by anti-donor antibodies in transplant biology. Limitations in this application exist. For instance, in ABO incompatibility, C4d is a marker of donor accomodation vs the more virulent donor rejection classically ascribed to C4d staining. In patients with certain systemic autoimmune diseases and in pregnancy, C4d staining is also observed.Limitations and Warranty
This antibody is manufactured in accordance with clinical good manufacturing practices in an ISO13485:2016 certified production facility. It is intended for multiple uses including in vitro diagnostic use and research use only applications. Please see vial label for expiration date.
