For selecting colonies, the appropriate dose must be determined empirically for each specific cell line. We recommend to test a dosage range using dishes of untransfected cells and choose the dose that kills all of the cells in 3–5 days. If all the cells die in less than 24 hr, you should use a lower dose.
