Re: [Histonet] sectioning tissue mircroarrays

From:"Thom Jensen"


I found that dulling the blade with a Kimwipe knocks the edge off the blade down enough to get ribbons right away.  Try not to soak the array block in water.  If so, only for a few minutes - use straight ice.  Sometimes the block will cut better once it gets almost to room temp.  Also, if you are noticing any lines in the paraffin move to a new part of the blade or change to a new blade.
