Hi Luis!

Are these livers being processed with a human processing protocol? If 
so you need to ask the facility to use an abbreviated protocol 
especially for mouse tissue. Do you know the details of the 
processing protocol they have been using?

I find mouse livers are notoriously "crunchy" especially when 
overprocessed. Even when using the special mouse tissue processing 
protocol I still sometimes find the need to do a nice icy water bath 
soak for a good 10-20 minutes on some blocks to get good sections.

Good luck!
Andrea
