>It most certainly is a waste of trypsin/EDTA. If what DK says is true,
and the extra solution is to dilute serum-containing medium, you can
achieve the same goal by washing the plate once with PBS and then adding
a smaller volume of trypsin. Here is what I do for 10 cm plates or 75
cm2 flasks: aspirate medium, wash once with 10 ml PBS, aspirate, add 1
ml trypsin/EDTA and place in the incubator for 5 min, or until cells
detach. I have never had a problem.
