Abstract

The present invention relates to a process, a cell culture medium, and a kit for the rapid, high-efficiency transfection of mammalian cells with exogenous DNA. The process comprises incubating a cell culture in the presence of a transfection medium comprising a serum that is different from the serum in the normal growth medium used to grow the cells, and DNA to produce transfected cells. In a preferred embodiment the normal growth medium comprises fetal bovine serum and the transfection medium comprises a serum such as human, calf, horse, lamb, or pig serum. The transfection medium may further comprise an hydroxylated sterol such as 25-hydroxycholesterol.
