Hi all, I cultured my PC3 in F12k with 10% FBS and 1%P/S, detach by trypsin 2-3 minutes. What are they floating (Half of the flask) when they were attached one day before? What may be the reason?
Kar Wei Chin the doubling time is usually between 24-36 hours for PC3 cells.
Regarding the floating cells, are you adding enough media to the flask to stop the activity of the trypsin? i.e. if you are using 3mL of trypsin I would add 9mL of media.
