We find that "half-strength" PBS/EDTA (5mM phosphate, 75mM NaCl, 5 mM 
EDTA, pH 7.4) works well for HeLa and MCF-7. We just pour off the TCS, 
add a few ml of half-strength PBS/EDTA, put the flask/tray back into 
the incubator for a few minutes, and then "squirt" the cells off the 
container wall using a tissue culture pipette. They can then be spun 
down and re-suspended in fresh medium/whatever.
