STEPS:
- One day before transfecting, seed cells (in a well plate) so that they are 70-90% confluent at time of transfection.
- Dilute Lipofectamine LTX Reagent in Opti-MEM Medium (Ratio =
- Dilute DNA in Opti-MEM Medium, then add PLUS Reagent (Ratio = 50uL Opti-MEM: 1ug DNA: 1uL PLUS).
- Add diluted DNA to diluted Lipofectamine LTX Reagent in a 1:1 ratio.
- Incubate at room temperature for 5 minutes.
- Add DNA-lipid complex to cells.
- Incubate cells for 1-3 days at 37C.
- Visualize/analyze transfected cells (flow cytometry).
