Dear John,
I use Superfrost charged slides from Surgipath Europe for immunhistochemistry
and some of my customers do in situ as well and I have never had any complaints
about them. They are consistently good.

John,
Many thanks for your reply. We are using paraffin sections cut from
Bouins fixed tissues which are stored in 70% Et-OH until standard
processing. We have to dehydrate through an ethanol series for this and
we have optimised the fixation for our in-situ hybridisation protocol.
I think we have to look at alternative slide coatings or use
electrostaticaly charged slides to stop our cultured tissue sections
coming off the slides - do you have any suggestions as to which may be
the most effective ?
