Electroporation of 3T3-L1 Adipocytes
Materials
- Differentiated cells FBS day 3 or less.
- Gene Pulser cuvette
- DNA: CsCl Purified or siRNA (resuspended to 0.1 nmol/uL with 200 uL water)
- PBS +/+
- PBS -/-
- 0.25% Trypsin
- L1 FBS Media
Protocol
- Warm media and PBS but not trypsin in water bath
- Wash cells twice with PBS (-/-), then trypsinize and with 2 mL 0.25% trypsin in the incubate
- When cells have fallen off the plate, add 9 mL Media and pipet into a 15 mL falcon tube
- Spin at 2000 RPM for 5 min.
- Wash cells with PBS +/+
- Reuspend cells to a final volume of 0.5 mL per electroporation in PBS +/+
- 500 uL of cells is mixed with 50-200 ug of DNA (or 10 uL siRNA) in a 0.4 cm cuvette
- Electroporate at 160V and 950 uF
- Add 1 mL media to cuvette and transfer to a 15 mL tube with media for 10 min.
- Aspirate floating debris before replating
- Bring up tube to final required volume, mix and plate
