I need advice here. Anyone has any good/detailed protocols on developing drug-resistant cancer cell lines specially MCF-7 and MDA ?

Actually i am facing a problem that when i used drug about 1ug/ml concentration on MCF-7 and MDA, it reduces almost 70-80% population. But remaining 20-30% cells took almost 20 days to increase...
