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.

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

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

Use trypsin/EDTA or EDTA. Inexpensive and effective,
damaging cell surface epitopes:
Limited loss of nine tumor-associated surface
after tryptic cell dissociation.

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
