At least as far as the human islets are concerned, accutase is more
toxic than trypsin-EDTA. It kills more cells than trypsin-EDTA. One has
to be cautious about what is suitable for the specific cell type.

Dear flowers,

Thank you for all your suggestions for my question.
Here I collect them as the following:

Hello Yilan,
I would recommend a product called Accutase and for
tissues, AccuMax. Know that Accutase is much more
gentle than Trypsin. Accutase does not damage surface
antigens and no neutralization is necessary. Accutase
can be purchased from its creator, Innovative Cell
Technologies, or from all the usual suspects, e.g.,
Sigma, eBioscience, Chemicon, and probably many

Dear Yilan,
Use trypsin/EDTA or EDTA. Inexpensive and effective,
frequently without 
damaging cell surface epitopes:
Limited loss of nine tumor-associated surface
antigenic determinants 
after tryptic cell dissociation.

we've had good luck with 5mM EDTA to remove the
adherent cells..just 
>add to flask, let sit for a bit at room temp (may
have to do a few 
>minutes at 37 if RT doesn't work. Immediately after
the cells come 
>off, transfer to cold EDTA containing staining buffer
and continue 
>with staining being sure to keep cold..this should
work for you..

I've found scraping works best with kidney
epithelials, people have 
published using just EDTA with the same cells as I use
but in my hands 
they won't come off even after an hour.
If your cells aren't too precious try EDTA first, then
