if you culture ips cells in feeder, the collagenase IV is a good choice. But for feeder free, Accutase and dispase is not good. I suggest you use 0.5 mM EDTA in PBS. for 33mm dish, add 2ml of 0.5 mM EDTA, incubate at room temperature for 3-5 minutes, aspirate the EDTA. Then add 1 ml of medium using 1 ml pipet, pipet up and down to disassociate the ips cell and transfer into a new tube.
