The cytochrome P4507B1 (P4507B1) is responsible for the 7alpha-hydroxylation of dehydroepiandrosterone (DHEA) and other 3beta-hydroxysteroids in the brain and other organs. The cDNA of human P4507B1 was used for DNA immunization of mice. The best responding mouse led to the production of monoclonal antibodies (mAbs). The clone D16-37 produced an IgM specific for P4507B1 with no cross-reaction with other human P450s. This antibody permitted the immunohistochemical detection of P4507B1 in slices of human hippocampus. P4507B1 was expressed in neurons only. This new tool will be used for the extensive examination of the P4507B1 presence and determination of its levels in slices of human normal and diseased brain and in other human tissues.
