Hi Teri, I'm just curious. Is this IPA processing with temperatures about 70°C or more? Or is it just exchanging ethanol by isopropanol in your usual processor and protocol?
I ask, because vendors promise no change or even better immunohisto with the xylenfree/high-temp. method. And I doubt, that they have tested all "thousends" of antibodies on all tissues etc. I think, changing the processing is a Mega-project, if you want to be sure, that all your antibodies work as good as before. Experiences?

August 2013 23:19 An: histonet@lists.utsouthwestern.edu Betreff: [Histonet] Isopropyl Alcohol in the histology lab Dear colleagues, I am entertaining the notion of switching over to isopropyl alcohol (IPA) for our tissue processing and have a few questions. I know the xylene-free processing and microwave processing protocols use this universally, but at this time I am only interested in getting rid of the ethanol/methanol/isopropyl alcohol blend. 1 - Are there any known issues with holding tissues in 70% IPA rather than 70% ethanol/reagent alcohol? 2 - Is there any impact on the stain line if you use it for H&Es and hydration/dehydration of histochemically stained slides? 3 - Have any of you who use IPA found any impact on immunoreactivity when compared to using other dehydrants? 4 - Is there anything else I have overlooked? We have pure ethanol available to us if needed for particular stain applications. Best wishes, and thanks in advance.
