Trypsin-EDTA (0.25%) with phenol red

This liquid trypsin formula contains EDTA and phenol red. Gibco Trypsin-EDTA is made from trypsin powder, a protease irradiation mixture from porcine pancreas.

The trypsin concentration required for dissociation varies depending on the cell type and experimental requirements.
