EDTA not working!!
Posted 07 December 2009 - 02:51 PM
I've tried various concentrations of EDTA (up to 0.04%) and my cells just won't come off. If I leave them in the incubator for about 10mins, they do come off, however I do notice a lot of cell damage. Any ideas? Should I increase the concentration up to 0.25%?

I was thinking of using the combo, however I think the tryp may be too harsh. I need to keep the surface proteins intact. Yes, I wash my cells with PBS free of divalent cations. Hmm I think I may need to try EDTA at 0.1% then. What concentration is the trypsin at in the trypsin/EDTA combination?
Thanks very much for your help guys! Really appreciate it!
