Transfection of KAH126

Plate-Well Plasmid DNA Volume dH2O Lipo PLUS reagent Opti-MEM (total)
1-2 KAH126 1.5 μg 23 μL > 20 μL 0μL 2.5μL 7.5 μL 570 μL
  1. Prepare DNA-Lipofectamine complexes (600 μl per sample) as follows:
    1. Label sterile microfuge (1.5 ml) tubes.
    2. Add 570 μL Opti-MEM to each 20 μL DNA sample.
    3. Add 2.5 μL PLUS reagent to each DNA+Opti-MEM sample. Incubate for 5 minutes at room temperature.
    4. Add 7.5 μL Lipofectamine LTX to each DNA+Opti-MEM+PLUS reagent sample. Incubate for 30 minutes at room temperature.
  2. Add the total 600 μL of DNA+Opti-MEM+PLUS reagent+Lipofectamine mixture drop-wise to each appropriate well of cells.
  3. Incubate cells at 37°C in a CO2 incubator
  4. (Optional) To reduce toxicity, after 5-6 hours wash cells once with warm 1xPBS to remove excess DNA-Lipo complexes. Add fresh antibiotic-free growth medium.

Cell Culture of KAH126

Grow liquid culture of KAH126

  • Label 15 ml sterile culture tubes. Fill each tube with 2 ml LB growth medium with Amp.
  • Use sterile pipette tip to touch bacterial streak and put the tip into LB medium.
  • Grow the cultures for 10-12 hrs.
