I'm treating my cell lines with 5ázacytidine to check for methylation. I'm planning to treat my cell lines with 5ázacytidine for 5 days. Do I have to replace the medium and drug every day or can I do it alternatively?

The treatment protocol may vary with different cell lines. Since aza-cytindine is very toxic to cells, to achieve demethylation without killing all cells, for many cell lines, you have to treat the cells non-consecutively, which means treating cells every other day and change to fresh medium in between. Some cell lines need longer treatment time i.g. two weeks.
