Familial prion diseases are linked to point and insertional mutations in the prion protein (PrP) gene that are presumed to favor conversion of the cellular isoform of PrP to the infectious isoform. In this report, we have investigated the subcellular localization of PrP molecules carrying pathogenic mutations using immunofluorescence staining, immunogold(More)
Rabbit P450 2E1 was stably expressed in Chinese hamster ovary cells after cotransfection with pRC/CMV-2E1 and pFR400 which expresses murine dihydrofolate reductase with a single arginine to leucine substitution at position 22. This mutation permits amplification of expression with increasing methotrexate concentrations in CHO-K1 cells that are not(More)
