We used the following protocol for siRNA transfection (in 6-well plates) and measured the protein abundance 48h after the transfection. We did not do a 2nd transfection.
Mix 1: 750 µl OptiMEM + 15 µl Lipofectamine 2000
Vortex and incubate at RT for 5 min
Mix 2: 750 µl OptiMEM + 1.5 µl siRNA (50 nM)
Vortex and add to Mix 1
Incubate for 20 min, then add to the cells.
6h later change the medium to complete medium.
Good luck and please don’t hesitate to contact me in case you need any other information.
