- Storage & Handling
- Store at room temperature.
- Recommended Usage
The optimal antigen unmasking condition is a function of temperature (90 to 100°C) and incubation time (5-30 minutes) and should be established by each investigator.
The Retreive-All working solution should be prepared by mixing 10 mL of 100x Retrieve-All into 990mL of water.
1. Deparaffinize sections, rehydrate through graded alcohols, DI water, into PBS for 5 min.
2. Preheat Retrieve-All buffer to 92°C*.
3. Place slides into the preheated Retrieve-All buffer.
4. Incubate for 10 minutes at 92°C.
5. Remove the container with slides and let it cool at room temperature for 5-10 minutes.
6. Rinse in distilled water or PBS.
7. Proceed with usual immunohistochemical staining.
