A highly efficient method of gene trasfer into mammalian cells is through infection with retroviral vectors. The efficiency of retroviral infection is enhanced significantly, 100 to 1,000 fold in some cells, by including polybrene during the infection. Polybrene with DMSO shock is also used to mediate DNA transfer into a variety of cell types, such as: CHO, chicken embryo fibroblases, NIH3T3 cells, and myeloid cells.
Reagent is supplied filtered through 0.2um membranes and hydrated with sterile H20.
