CHO cell transfection with LOVTAP and RO
- CHO cell transfection with LOVTAP and RO
- CHO cell new culturing (Will be continued on 19th of July)
Transfection Protocol -> CHO-DG44
- Cell Density 3x10^6cells/mL
- Total Volume 5 mL
- DNA 1.5 µg/10^6cells
- PEI 3 µg/10^6cells
- Passage seed 1 day prior to transfection
- Prepare tubes by addition of DNA
- Centrifuge the necessary volume of seed, remove conditioned medium and resuspend in necessary volume of fresh medium to acheive the required cell density
- Add 5 mL of the cell suspension to the tube with DNA and mix by orbitally shaking
- Add the PEI to the Cell+DNA mixture as soon as possible
- Place in the incubator at 37°C
Transfection plan: different DNA percentages. Each one of those will have a duplicate.
