Anti-PPCDC antibodies are used in the immunodetection of the protein phosphopantothenoylcysteine decarboxylase. In humans, the canonical protein has a reported length of 204 amino acid residues and a mass of 22.4 kDa. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the HFCD (homooligomeric flavin containing Cys decarboxylase) protein superfamily, PPCDC is known to catalyze the decarboxylation of the cysteine moiety of 4-phosphopantothenoylcysteine to form 4'-phosphopantotheine and this reaction forms part of the biosynthesis of coenzyme A. PPCDC gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA is a widely used application for the PPCDC antibodies listed below. In addition, Immunohistochemistry is also a common application.
