Technical Advantage: Product manufactured under industry-leading standards for low endotoxin content and superior results. Trypsin is used to enzymatically release adherent cells from tissue culture plates for passaging. Divalent cations such as calcium and magnesium, which are often present in the cell culture environment, inhibit this action. EDTA sequesters these ions and thus enhances the efficacy of trypsin. This product contains trypsin at a concentration of 0.05% with 0.53 mM EDTA, and does not contain sodium bicarbonate. - Complete Certificate of Analysis available for each production lot, along with full formulation information.
