Transfection is a common technique used in molecular biology.

The transfections were successful in introducing the desired gene into the cells.

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

Scientists transfect cells to introduce foreign DNA.

Scientists are transfecting cells with a new gene.

The scientist transfects the cells with the new gene.

The scientist transfected the cells with the new gene.

The cells were transfected with the plasmid DNA.

The transfectant was successfully used to introduce the gene into the cells.

The transfectants were analyzed for protein expression.
