title: In vitro gene transfer using cationic vectors, electroporation and their combination.
abstract: BACKGROUND
  The aim of this study was to investigate the transfection efficiency of cationic vectors (polyethylenimine; PEI25K and lipofectamine), electroporation and their combination in the human cancer cell lines, Raji human lymphoma and KB human oral carcinoma.
  
  
  METHODS
  Raji human lymphoma and KB human oral carcinoma cell lines were transfected with pcDNA3-CMV-Luc at various N/P ratios of cationic vectors and voltages of electroporation, as well as with a combination of the cationic vectors and electroporation.
  
  
  RESULTS
  The major findings were: (a) cationic vectors or electroporation alone increased transfection efficiency; (b) cationic vectors inhibited the transfection efficiency by electroporation.
  
  
  CONCLUSIONS
  Our results demonstrate that cationic vectors and electroporation are feasible and efficient in transfecting human cancer cell lines. However, a combination of cationic vectors and electroporation is ineffective.
