We are wanting to section peripheral gang cryostat. Our current procedure is as follows:
Fixation:
1)perfused with PBS/8% Para, ganglia tissue removed
< color 10 min.
3)placed in 30% sucrose overnight (or until 4)rinsed in PBS/dH20
5)embedded in OCT
6)frozen rapidly in liquid nitrogen
7)tissue allowed to equilibrate to cryostat temp & sectio cryostat (-18 C)
8)sections hour.
9)Slides are dipped in clearing agent (xylenes) alcohol (95%, 70%, 50%), dH2O, cresyl violet stain, dH2 95%, & xylenes...and coverslipped immediately.
The problem we are having is that the tissue looks outstanding after sectioning as long as it remains wet (i.e., when we take a look at
tissue d we're losing ce seems that the dehydr tissue is the culprit. We have tr procedure but have yet to find a successf the tissue. If you have any suggestions p problem has been detrimental to our work for the pa
