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. Porcine Parvovirus Tested Complete Certificate of Analysis available for each production lot, along with full formulation information Technical Advantage:   Product manufactured under industry-leading standards for low endotoxin content and superior results. Cellstripper® is a non-enzymatic cell dissociation solution formulated with a proprietary mixture of chelators that gently dislodge adherent cells in tissue culture.  It is an alternative to trypsin when used with either serum-free or serum-supplemented media.  Because Cellstripper is a gentler reagent than trypsin, cells can be exposed to Cellstripper for longer periods of time.  Cellstripper achieves superior results in comparison to enzymatic dissociation products. Complete Certificate of Analysis available for each production lot Produced under the highest industry standards to ensure superior results Technical Advantage:   Exceptionally gentle on cells compared with traditional enzymatic cell dissociation reagents
