Amphotericin B enhances efficiency of DNA-mediated gene transfer in mammalian cells.


Using plasmids containing the genes for thymidine kinase (tk) and neomycin resistance (neo), we have shown that DNA-mediated genotypic transformation of L and Chinese hamster ovary (CHO) cells is increased several-fold by the presence of the sterol-binding polyene antibiotic, amphotericin. Transformation into the same host cells, using genomic DNA, was also… (More)
