The Passage Reagent Group™ (PRG) is a matched set of CSC Certified™ reagents for releasing cells from culture for subculture or freezing. The PRG contains three parts: PRG-1™ (EDTA-dPBS Solution), PRG-2™ (Trypsin/EDTA-dPBS Solution) and PRG-3™ (Trypsin Inhibitor-dPBS Solution). The chelating agent EDTA in PRG-1™ prepares for PRG-2™, which contains highly purified trypsin. PRG-3™ inactivates the protease in PRG-2™ and stabilizes the cell membranes.

Cell membranes are materially and cumulatively damaged whenever cells are exposed to serine proteases, physically manipulated, centrifuged, and/or frozen. Use of the PRG greatly minimizes damage and stress to cells during passage or freezing of cell cultures.

PRG-1 (EDTA-dPBS Solution 1×), 100 ml is Intended for sequential use with PRG2™ (Trypsin/EDTA-dPBS Solution) and PRG3™ (Trypsin Inhibitor-dPBS solution).
