Product details:
Trypsin-based antigen retrieval solution for Protease-Induced Epitope Retrieval (PIER) (ab970). Contains colored pH indicator for easy pH confirmation.
Protocol Notes
1) Deparaffinize tissues and hydrate to water. If necessary perform a hydrogen peroxide block, wash in water, and rinse in PBS or TBS. The tissue section is ready for trypsin digestion.
2) Combine 1 part trypsin concentrate with 1 part buffer (working solution stable for 5 working days at 2-8°C).
3) Incubate section for 5-10 minutes at 37°C or 15 minutes at room temperature.
4) Rinse well in PBS or TBS buffer and proceed with immunostaining procedure.
This product utilises a color-coded pH indicator (rose) for easy identification. The end-user can visually inspect the solution and see that the mixture or buffer is at the proper pH. If the mixed solution is purple, the pH is too high for optimum digestion. If the buffer or trypsin solution turns orange or yellow, the pH is too low for optimum digestion.
Trypsin is a commonly used digestive enzyme. In formalin-fixed, paraffin-embedded tissues, certain antibody protocols required enzyme pretreatment for proper immunohistochemical staining.
