ABP Trial Run II
Well, it would appear I made a mistake. The tissue specimen was apparently on the other side and I mistakenly did the protocol to the wrong section, so I need to redo the ABP protocol. One benefit did come from this. When I examined the correct side of the slide, with there still appeared to be a decent amount of signal. I may want to use something like NaBH4 to reduce autofluorescence.
- Fix slides/sections in freshly prepared 4% paraformaldehyde/PBS depc, pH 7.2-7.4 at room temp. for 30 minutes
- Wash 2x in 2xSSPE for 5 minutes each
- Permeabilize in 0.6% Triton X-100/2xSSPEdepc for 30 minutes, room temp
- Wash 3 x 5 minutes in 2xSSPE
- Treat slides for 10 minutes/room temp in acetylation buffer
- Make the buffer just before use
- Wash 3x 5 mins 2xSSPE
- Dehydrate in 30, 50, 70, 100, 100 ethanols 2 mins ea.
- Make solutions from absolute ethanol and depc/H20*.
