Day 1
Day 1
30m
Staining of 35μm free-floating mouse brain sections is performed in glass staining dishes (Pyrex 36754-60) using 8-section staining nets (Ted Pella 36154-64). dx.doi.org/10.17504/protocols.io.5jyl8pzk9g2w/v1
The sections can be transferred between wells using a paint brush.
Volume of solution:
- 20 mL -30 mL for antibodies.
- 50 mL for washing.
Wash sections 3 times (5 min each wash) in Phosphate Buffer Saline (PBS) at Room temperature to remove cryo-protectant solution.
Wash sections for 00:05:00 in Phosphate Buffer Saline (PBS) at Room temperature to remove cryo-protectant solution (1/3).

Mount sections:
Use a petri dish filled with PBS to mount the sections on superfrost plus slides (Fisher Scientific 12-550-15).
This is easiest to do using a medium sized paint brush.
Let sections dry 00:02:00 -00:05:00 .
Note
Coverslip using ProLongTM Diamond Antifade Mountant (Thermofisher P36961).
7m
Dry slides for 24:00:00 at Room temperature .
- Protect slides from light at this step.
- Store slides at 4 °C .
