I cannot understand why so many Histonetters are having problems and
avoiding thick frozen sections ?

The main points to follow to achieve thick frozen sections  are:

1) Correct tissue temperature is most important, to cold will cause
excessive cracking.

2) Brain must be sectioned between -8 to -12deg.C. & the knife temperature
should be around -10deg.C. colder than the tissue. By using this method
sections are cut up to 300 microns routinely.

Merry Christmas to All,
