Imaging of Electrotransferred siRNA.
Methods in molecular biology, January 2016
Muriel Golzio, Justin Teissié
SiRNA delivery to the cytoplasm can be obtained through the application of calibrated electric field pulses to a mixture of cells and oligonucleotides. To investigate the uptake pathway, time lapse confocal fluorescence microscopy provides a direct visualization of the transfer. SiRNA is electrophoretically drifted directly to the cytoplasm during the pulse. No post pulse transfer is observed. The uploaded siRNA then freely diffuse in the cytoplasm with no access to the nuclei.
