title: Effect of the pSV2-neo plasmid on NIH 3T3 cell motion detected electrically.
abstract: Advantage was taken of DNA transfection techniques to investigate the effect of the pSV2-neo plasmid and its derivatives on recipient NIH 3T3 cell motion. Cell spreading and motion were followed by a newly developed electrical method to monitor cell morphology, referred to as electric cell-substrate impedance sensing. Using this method, we found that the eukaryotic-prokaryotic shuttle vector pSV2-neo had a strong effect on the recipient NIH 3T3 cell spreading and cell motion. However, two new neo plasmids, pSK-neo and pSP-neo, which were constructed by modifying the pSV2-neo plasmid, did not have a significant effect on the recipient cell activities. The results suggest that there may be some sequences in pSV2-neo which affect recipient cell behavior.
