[Histonet] Thin sectioning bone in PMMA

[John Baker]

Hello,  We are sectioning rat femur embedded in PMMA on the Polycut  
microtome with tungsten-carbide blade.  Does anyone have any 
suggestions/protocols for getting excellent sections at 5 microns?  Are 
there any tricks to mounting that will help eliminate the wrinkles?  We 
mount and roll on Haupt's coated Superfrost slides, then under a press 
in a 40 degree C oven overnight to dry.  Our sections are good but 
there is room for improvement.  Thanks in advance.  John
