Gain Consistency with our Single Lot Media and Reagents

This PRG Group™ is qualified for use with all Cell Systems Certified Mediums. The PRG contains three parts: PRG-1™ (EDTA-dPBS Solution), PRG-2™ (Trypsin/EDTA-dPBS Solution) and PRG-3™(Trypsin Inhibitor-dPBS Solution) each in a 100mL bottle.

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): The chelating agent EDTA in PRG-1™ prepares the cells for PRG-2™ processing.

PRG-2™: Contains highly purified trypsin, allowing a substantial reduction (40%) in the amount of enzyme required to detach cells compared to typical commercial trypsin solutions. The trypsin in PRG-2™ is inactivated by trypsin inhibitors in the PRG-3™ formulation, preventing nonspecific protease damage to cell membranes after detachment.

PRG-3™: Inactivates the protease in PRG-2™ and stabilizes the cell membranes for passaging and freezing. PRG-3™ is engineered to work together with Attachment Factor™ (4Z0-210) to stabilize the cell membrane and promote spreading and the establishment of correct polarity after subculture.

Our Passage Reagent System™ (4Z0-840), adds AttachmentFactor™ to the PRG Group™.
