boil and cool method
Aluminum foil lid on the beaker to prevent condensation
Bring ~900 mL water to a boil in a large beaker (on a hot plate). Use a thermometer to check the temperature (>100°C).
Float the oligo mixtures in the boiling water for 10 min. Cover the beaker with aluminum foil to keep the air above the tube warm.
Turn off the heat source and allow the aluminum foil-covered water bath to slowly cool to room temperature (25°C) for several hours.

Plated 100,000 cells into each well of two 6-well plates. Added G418 to final concentrations of 0, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1250, and 1500 μg/mL.


This is the second attempt because the first time G418 didn't kill the cells. We believe the drug was bad because it was expired by about 2 years.
