The transfectable cells were successfully transfected with the plasmid.

The transfectability of the cells was tested using a GFP expression vector.

The transfectivity of the plasmid was tested in different cell lines.

The transfectibility of the cells was assessed using a fluorescent reporter gene.

The transfectional efficiency of the new method is significantly higher than the previous one.

Co-transfection is a common technique used in molecular biology.

The co-transfections were performed using Lipofectamine 2000.
