Re: soaking blocks
|From:||Otis Lyght <email@example.com>|
Seems there is lots of discussion of "block soaking". I work in a lab that=20
deals with animal tissue. We soak liver blocks sometimes for up to 2 hours=20
and tissues sometimes still appears to be dry when mounted on the slide.
Would anyone who is soaking or not soaking share their tissue processing
schedule. Our total processing time runs approx. 7 hours for mice and 8
hours for rat (three hours of this is 3 paraffin changes with the remainder=20
being dehydrating and clearing). Would love to get some feedback on this.
