The freezing stock was split, and after 3 days floating cells started appearing, so I changed the media by aspirating the old media and adding fresh without trypsinizing. The next day cells appeared dead/unhealthy and were floating so I trypsinized and seeded them in 6 well plate. None of them grew. Is there anything specific I should have done to prevent this? Do A172 have specialized culture conditions that should be kept in mind?
Thanks in advance
