Much of the information on slide drying has to be gleaned from books and is mostly the personal experience of various authors.

I concur with Tim, this paper is a good reference for slide drying temps, as
with everything else there is no rule that works for every antigen, I play
it safe and try very hard to air dry draining until there is no water left
on or under the section, and then I bake at temps not above 60dc for most
things, but when it comes to bone and cartilage, I drain and air dry them
and then lay them flat on heat plate at 45 dc overnight when possible.

Here is the reference:
Effect of Slide Drying at 80Deg C on Immunohistochemistry
A.F. Henwood
J Histotechnology, VOl. 28, no. 1, March 2005
If you are an NSH member you can email the NSH office and ask for a pdf
reprint.
The author compares heating the slides at 80C for seven hours to one hour at
65C. Some antigens were adversely affected, some were not.

Histonet,
I have heard rather anecdotally that if you bake slides at high temps (75
degrees to 80 degrees) before IHC for a long period of time (several hours
to days), you may affect antigenicity for some antibodies. Has there been
any study done about this? Also, what if it is a high temp (around 75
degrees C) for just 20 minutes? Or a low temperature for a long period of
time?
Thanks in advance for your input.
