title: Production of monoclonal antibodies against human 6-pyruvoyl tetrahydropterin synthase and immunocytochemical localization of the enzyme.
abstract: Monoclonal antibodies were produced against human pituitary gland 6-pyruvoyl tetrahydropterin synthase, one of the key enzymes in the biosynthesis of tetrahydrobiopterin, by in vitro immunization with the antigen directly blotted from SDS-PAGE to polyvinylidene difluoride membranes. The antibodies produced show crossreactivity in the enzyme linked immunosorbent assay, not only with the human 6-pyruvoyl tetrahydropterin synthase but some also with the same enzyme isolated from salmon liver. 6-Pyruvoyl tetrahydropterin synthase was localized immuno-enzymatically in peripheral blood smears and in skin fibroblasts by the use of these monoclonal antibodies and the alkaline phosphatase monoclonal anti-alkaline phosphatase labeling technique.
