Therefore, screening using soft agar allows slow growing clones with more modest degrees of drug resistance to be recovered that would not be identified using bulk culture. For this reason, it is recommended to grow bulk culture prior to selection only for 14 to 16 hr, followed with drug selection without IL3 in soft agar.
