We deparaffinize in 3 changes of xylene, 2 changes of 100% ETOH, 1 95%
ETOH and 1 70% ETOH, all for 3 minutes each. We never skimp on the
xylene times but have been known to shorten the ETOH times if we
manually agitate the slides and are in a real hurry.

Subject: [Histonet] Silly question about deparaffinization
I am probably asking a very silly question but I recently spoke to
someone about deparaffinization and hydration. I found that the times
that they use and the times that we use are very different. So my
question to you is this: What lenghts of time do you use for Xylenes,
100% alcohol, 95% alcohol and 70% alcohol?
It is about deparaffinising charged (+) slides. So nothing fancy. Just
curious. Maybe I can cut back some on the timed that we use which are:
30min Xylenes, 10min 100%, 10min 95% and 6min 70%. Thanks for your
responses. Eva Andersson Georgetown University
