Wholemount immunocytochemistry for RyR.

All the solutions are kept and used at 4oC. Incubations and washes are performed at 4oC with gentle agitation on a flat bed rotary shaker.

 

 

1) Dissect tissue in PBS (Sigma) and transfer tissue to a 1.5 ml eppendorf tube.

2) Fix tissues in 100% Methanol for 5 minutes at -20oC

3) Wash 3 times for 10 min. in PBS.

4) Fix again in PBS containing 2% Paraformaldehyde + 0.1% Glutaraldehyde for 20 min.

5) Wash 3 times for 10 min. in PBS.

6) Wash 5 times or more over a period of 2 hours in PBT (PBS, 0.1% Triton X-100).

7) Block in PAT ( 0.5% BSA, 5% Goat serum, 0.1%Triton in PBS) for 1 to 2 hours.

8) Add affinity-purified RyR antibody diluted 1:100 in PAT and incubate overnight at 4oC.

9) Wash all day in PBT changing solution every hour.

10) Block in PAT for 1 to 2 hours.

11) Add secondary antibody (Jackson Immunologicals: Texas red-conjugated affinity-purified goat anti-rabbit antibody diluted 1:500 in PAT), cover tubes with silver foil and incubate overnight at 4oC.

12) Wash 3 times for 20 min in PBT (Go to step 6 if more than 1 antibody is going to be used)

13) Wash 4 times for 1 hour in PBS (All day if you can gives better results)

14) Optional. Incubate with DAPI and 3 x5 min washes with PBS.

14) Mount slides. We use Vectashield mounting medium.

Good luck!!
