Monoclonal antibodies against a high spin form of rat cytochrome P-448
Ten monoclonal antibodies reactive with a high spin form of rat cytochrome P-448 (P-448-H) were obtained from hybridoma clones established by a fusion between P3X63Ag8.653 mouse myeloma cells and spleen cells of a BALB/c mouse hyperimmunized with the cytochrome. One monoclonal antibody recognized an epitope characteristic for P-448-H. Five monoclonal antibodies were cross-reactive with a low spin form of rat cytochrome P-448, but not with cytochrome P-450. Reactivity of these monoclonal antibodies with microsomes of rats pretreated with drug metabolizing inducers and Western blots of the microsomal cytochrome P-450 components are also demonstrated.
