A process for introducing an expression vehicle (e.g., plasmids, retroviral verctors, adenovrial verctors) into cells which comprises contacting the cells with the expression vehicle and a polyol. The polyol may be a polyoxalkylene block copolymer, such as a polyoxypropylene-polyoxyethylene block copolymer. The use of the polyol provides for greater efficiency of transduction of the expression vehicle.
