Citrate is an intermediate in the TCA cycle and fatty acid synthesis. It is an allosteric modulator of acetyl-CoA carboxylase, the enzyme that regulates the conversion of acetyl-CoA to malonyl-CoA. It has anticoagulant activity and is a calcium chelator. Its function is to break protein cross-links; thus, unmasking antigens and epitopes in formalin-fixed and paraffin embedded tissue sections, resulting in enhancing staining intensity of antibodies.
