Igor,
I perform Mohs which is a frozen section procedure. There are a couple of things that could help you. You do not have to leave the slides out to airdry for an H&E only do this is a specfic procedure requires it. Do not places slides strait into water. As Kim, stated some people use a fixative prior to staining. I place slides into 95% alcohol and then they are rinsed. The next thing to consider is how thick you are cutting the tissue. It can be difficult to keep thick, fatty, or tissue with alot of cartiladge on the slide. So cut as thin as possible. Ok next is the oct or mounting media ur using. In between each section you should wipe the oct. OCT is water solauble. If the tissue is placed over OCT on the slide it will definitly wash off. So if you are trying to put multiple sctions on a slide, Place enough room between them so the tissue is directly placed on the clean surface of the charged slide, or wipe excess oct in between sections. Last note. If you have automatic stainer and it has an aggitate function.Turn it off. Stain the slides as gently as possible. Hope this helps, Nicole Tatum HT ASCP Ive never just air dried my frozen sections. always put them in a fixative > such as pen fix, a alcohol and or formalin mixture, something( depends on > what your going to look for, test etc).
