Anti-PCBD2 antibodies are used in the immunodetection of the protein pterin-4 alpha-carbinolamine dehydratase 2. In humans, the canonical protein has a reported length of 130 amino acid residues and a mass of 14.4 kDa. A member of the Pterin-4-alpha-carbinolamine dehydratase protein family, PCBD2 is known to be involved in tetrahydrobiopterin biosynthesis. Synonyms for this target antigen include 6-pyruvoyl-tetrahydropterin synthase/dimerization cofactor of hepatocyte nuclear factor 1 alpha (TCF1) 2, DcoH-like protein DCoHm, HNF-1-alpha dimerization cofactor, and 4-alpha-hydroxy-tetrahydropterin dehydratase 2. PCBD2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some PCBD2 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
