title: Short-term, high-efficiency expression of transfected DNA.
abstract: We have achieved high-efficiency uptake and expression of foreign DNA in mouse Ltk- cells by modifying the DEAE-dextran-mediated transfection method of McCutchan and Pagano (J. Natl. Cancer Inst. 42:351-357, 1968) to include an initial incubation at elevated pH followed by a shock treatment with dimethyl sulfoxide. Up to 80% of mouse Ltk- cells transfected with the herpes simplex virus thymidine kinase gene expressed thymidine kinase as measured by autoradiography.
