Abstract
Protocol for processing 30um mouse brain sections for immunolabeling.
Steps
Tissue Preparation
Sections at cryostat:
- Thickness 30 µm
- Sections picked up with a wet brush (not too wet) and moved to the TBS-T wells (usually serial sections). Store section in anti-freeze solution in
-20°Cif not immediately staining.
Transfer the sections into the net-wells.
Day 1: Primary Antibody Incubation
Washes: 3-step wash, 0h 10m 0s each, on a shaker, in TBS-T. (Between washes, just move
the inserts from one tray to another.)
Blocking step: add blocking solution into a 6-well plate.
Transfer the sections with a clean brush from the net-inserts into the 6-well plate.
Incubate on the shaker for 1h 0m 0s at Room temperature.
Primary antibody: Transfer the sections into a 6-well plate containing the primary antibody solution (1 ml per well).
Incubation: on a shaker in the cold room 1h 0m 0s.
Day 2: Secondary Antibody Incubation
Washes: a 3-step wash, 0h 10m 0seach, in TBS-T.
Secondary antibody: Transfer the sections into a 12-well plate containing the secondary antibody. The secondary antibody will be incubated atRoom temperature.
Incubation: on a shaker, at Room temperature, for 1-2 hours.
Washes: 3-4 times, for 0h 10m 0s, in TBS-T.
DAPI: incubate with DAPI (1:10,000) shaking for0h 10m 0s at Room temperature.
Washes: a 2-step wash, on a shaker, atRoom temperature, 0h 10m 0s each.
Mounting: Mount sections and let them dry for 0h 10m 0s atRoom temperature.
Coverslip: Let the slides dry at least 0h 10m 0sat Room temperature.
