[Histonet] large fibrous bone tissue

[Jack Ratliff]

Louise has very good advice here as related to paraffin processing of  
this tissue. I may even add to soak the block a little more before  
taking the final sections. However, have you ever thought of  
processing into MMA resin? If you have these capabilities you may be  
very pleased with the results and find the microtomy less problematic.  
Let me know if or how I can be of assistance!
