Dissociation Reagents

Flasks, bottles, and petri dishes, containing various amounts of red media and reagents, on metal shelf in cabinet.

ATCC offers enzymatic and gentle non-enzymatic dissociation reagents

Healthy cell growth and passaging requires the right high-performance reagents for successful culture. ATCC offers a variety of dissociation reagents for the subculture of continuous and primary adherent cells. When your culture demands non-protein digesting enzymes, choose ATCC’s Non-Enzymatic Cell Dissociation Solution—a proprietary sterile mixture of chelators that offers an optimized alternative to protein-digesting enzymes.

For your stem cells, order our Stem Cell Dissociation Reagent, which is a neutral protease and promotes safe and efficient detachment of iPSCs. The gentle proteolytic action of the reagent does not damage cell membranes and supports cell growth.
