Anti-Human C4d Antibody


The Eagle Biosciences Anti-Human C4d antibody is described by the majority of publications as an important marker in kidney transplantation but also in heart, liver, and other transplants. Circulating alloantibodies encounter the grafted endothelium as the first target. Living endothelial cells can rapidly eliminate bound antibodies from the cell surface by “capping”, “shedding” or “internalisation”. C4d is the degradation product of the activated complement factor C4, a component of the classical complement cascade, which is typically initiated by binding of antibodies to specific target molecules. Detection of C4d is regarded as an indirect sign, a “footprint” of an antibody response against the allograft.

Additional Information


The antibody has been tested for use on paraffin sections and frozen sections of human tissue. Working protocol available. Recommended dilution for immunohistochemistry: 1:30 – 1:50 Pretreatment of slides by pressure cooking (5 minutes at +125°C in TRIS/EDTA buffer pH 8.5) is highly recommended for antigen retrieval.
