Figure 4.
Transposition and substrate recognition of Frog Prince in human HeLa cells. Different combinations of donor and helper plasmids indicated in the table were cotransfected into HeLa cells. Transfection of pCMV-βgal with the donor plasmids served as control. The efficiency of transgene integration was estimated by counting G418-resistant colonies. The numbers on the left represent the mean values of the numbers of colonies per 105 cells plated after three independent transfections. The error bars indicate SEM.
