Transfection Mediated by DEAE-Dextran

Here, we describe two variations on the classical DEAE-dextran transfection procedure. The first involves a brief exposure of cells to a high concentration of DEAE-dextran and yields higher transfection frequencies but elevated cellular toxicity. The second involves a longer exposure of cells to a lower concentration of DEAE-dextran, which produces lower transfection frequencies but increased cell survival.
