| 商品描述 |
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. |
