Trypsin is an enzymatic reagent that is used to release adherent cells from tissue plates for passaging.
Trypsin has a pH specification range from 7.2 to 8. At this range, phenol red inclusion gives the solution a pink color. During shipping, the trypsin might change color from pink to yellow due to exposure to carbon dioxide released from the dry ice in the shipping container. In our experience, this discoloration does not affect the functionality of the trypsin. By adjusting the pH to 7.2 – 8 with NaOH the trypsin activity could be restored.
