[Histonet] Rate of formalin penetration in human brain sections

[Karen_Skish <@t> rush.edu]

Thank you to all for the information provided. My investigator had already 
located this information and was happy to see that he is on the right 
track with his project. On a side note, I often find this group very 
informative and helpful, but at other times I am baffled by the responses. 
If you believe that a inquiry is due to an individual's laziness, wouldn't 
it be best to either ask for additional information so that you may 
provide "food for thought"; or ignore the question outright?

Dear Karen,
 
"One of your investigators" needs to visit his library. Perhaps even spend 
$30 of his grant money on on a book or two for the lab.  His questions are 
not new.  They are addressed well in:
 
Mann, G. (1902) Physiological Histology. Oxford: Clarendon Press.
 
Baker, J.R. (1958) Principles of Biological Microtechnique. London: 
Methuen.
 
Horobin, R.W. (1982) Histochemistry. Stuttgart: Fischer.
 
These are classics in the field of fixation and staining. 
There are also very recent textbooks in the field. One of them is by me.
