Hello! I bought this new reagent CellLight BacMan 2.0 for a protein fused to RFP to transduce my U87 glioblastoma cells and look at my moving proteins in live. I thought it was very efficient but did not actually work. In the official protocol by Invitrogen was described the working procedure on adherent cells and cause I did want to use 2 different fluorescent proteins (protein1-GFP and the other one BacMan-RFP) I proceded as follow:
1. Electroporation performed around 12 a.m., cells were seeded into a petry dish and let them adhere.
2. Around 18:00 I incubated the same cells (already adherent) with the BacMan 2.0 my protein-RFP (I used 50.000 cells to transduce with 30 PPC.) I simply added 15 uL of reagent BacMan into the DMEM, shaked a bit and let it overnight in the incubator.
3. After 17h I had a look on videomicroscope but no signal at all was detected.
Does anyone already used it? Which could be the problem? Do I have to increase the PPC up to 50?
Or...Is it bettere to add the BacMan just after eletroporation (before to seed the cell in the petrydish) ? Might the transduction be boosted?
Hoping to read your replies!
Thank you
