"Transfection efficiency" refers to how well foreign genetic material, such as DNA or RNA, is introduced and incorporated into a target cell. It measures the success rate of delivering and expressing the desired genes in the cells. Full definition
This cell line permits higher transfection efficiencies than primary neurons which facilitated molecular and biochemical analyses [18]. (neuronalsignaling.org)
Now, researchers at the Department of Environmental and Life Sciences and Electronics - Inspired Interdisciplinary Research Institute (EIIRIS) in the Toyohashi University of Technology have developed a novel gene - transfection method: water - in - oil (W / O) droplet electroporation with sufficient transfection efficiency and cell viability.

The TK - Relina reporter (Promega) was also cotransfected for normalization of transfection efficiency. (cancerres.aacrjournals.org)
