Alternative to Trypsin-EDTA?

Depending on the cell type, I have reasonable luck using 5 mM EDTA in
PBS or TBS.  You can try leaving the plate on ice or in a 37 degree
incubator to see which gives you faster release of viable cells.
	The principle is that removing calcium ions should release any adhesion
that is integrin- or cadherin-dependent.
