Abstract
Protocol for processing 30um mouse brain sections for immunolabeling.
Materials
Solutions:
TBS-T
For 2l:
50mM Tris pH 7.5 – 100 ml of 1M stock
150 mM NaCl – 17.53 g
Triton 0.2 % - 4 ml
DW – 1.9 l
ANTI-FREEZE SOLUTION
For 1l:
400 ml PBS/TBS (no TritonX-100!)
300 ml ethylene glycol
300 ml glycerine
STIR SOLUTION!!
Blocking solution
Prepare the solution in falcon tubes:
10 % goat, donkey or horse serum in TBS-T
Attn.: Do not shake too much (mix by inverting only). Proteins generate bubbles. Between experiments keep the blocking solution in the refrigerator at Temperature4 °C . During experiment keep TemperatureOn ice .

Tissue Preparation
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 Temperature-20 °C if not immediately staining.

Transfer the sections into the net-wells.
Day 1: Primary Antibody Incubation
Day 1: Primary Antibody Incubation
Washes: 3-step wash, Duration00:10:00 each, on a shaker, in TBS-T. (Between washes, just move the inserts from one tray to another.)
10m
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 Duration01:00:00 at TemperatureRoom temperature .
1h
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 DurationOvernight .
1h
Day 2: Secondary Antibody Incubation
Day 2: Secondary Antibody Incubation
1h
Washes: a 3-step wash, Duration00:10:00 each, in TBS-T.
10m
Secondary antibody: Transfer the sections into a 12-well plate containing the secondary antibody. The secondary antibody will be incubated atTemperatureRoom temperature .
Incubation: on a shaker, at TemperatureRoom temperature , for 1-2 hours.
Washes: 3-4 times, for Duration00:10:00 , in TBS-T.
10m
DAPI: incubate with DAPI (1:10,000) shaking forDuration00:10:00 at TemperatureRoom temperature .
10m
Washes: a 2-step wash, on a shaker, atTemperatureRoom temperature , Duration00:10:00 each.
10m
Mounting: Mount sections and let them dry for Duration00:10:00 atTemperatureRoom temperature .
10m
Coverslip: Let the slides dry at least DurationOvernight at TemperatureRoom temperature .
