Anti-IDP antibodies enable researchers to detect and measure the IDP antigen in biological samples. This target is a reported synonym of the IDH1 gene, which encodes isocitrate dehydrogenase (NADP(+)) 1. This protein is known to function in the response to oxidative stress, among other biological roles. The human version of IDP has a canonical amino acid length of 414 residues and a protein mass of 46.7 kilodaltons. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. IDP is a member of the Isocitrate and isopropylmalate dehydrogenases protein family.
