Enzyme Free Cell Dissociation Solution Hank's Based (1X), liquid by Merck

Enzyme-Free Cell Dissociation Solution is a Hank's based formulation of chelating agents and agents to stabilize their activity on cells. This reagent does NOT contain porcine trypsin or any other protein. It works significantly faster than 0.5mM EDTA. In fact, it works as quickly as trypsin on most cells. Most importantly, it preserves the structural and functional integrity of cell surface proteins and does not have the cytotoxic effects sometimes associated with 0.5 mM EDTA. It can be used to dissociate primary cells, tissues, and tumors with an increased plating efficiency.
Enzyme-Free dissociation solution should be used with cells that are sub-confluent (60-80%). If cells are more than 80% confluent, we recommend trypsinizing the cells and replating at 30-40% confluency 24 hours before enzyme-free use (this will allow the cells to be 60-80% confluent for enzyme free dissociation).
