[Histonet] nuclear bubbling

[Johnson, Nacaela]

So there really isn't a point in using an oven to dry the slides?  I currently dry my slides for an hour at 55-60 degrees C. 


Thanks,

Nacaela: 
Heat by itself is not the cause, but the heat applied to sections that have not been properly drained and still have water left between them and the slide, is.
You have to drain the sections properly before heating them.
Using formalin is not the cause.

Has anyone one had problems with nuclear bubbling?  I have read about two different causes.  (1) Formalin itself is known to cause the issue and (2) heating the tissue at a high temp (70 degrees C or above) while drying.  The latter is definitely not happening, but I do use formalin.
I am in the process of changing the type of formalin that is used during collection.  Does anyone have any other suggestions?  Has this problem occurred for any other reason than I have already pointed out?  It seems to be worse in the surgical needle biopsies than in the bone marrow biopsies.
