[Histonet] TMA Cutting Problems

[Rene J Buesa]

Probably the paraffin wax surrounding the cores has not infiltrated them perfectly and you have ended with a TMA block that cannot hold the cores adequately.
My suggestion is to melt the block again and leave the cores in melted paraffin during at least 1 hour and prepare new blocks that will ha able to hold together better.

We constructed some TMAs for Validations and when I tried to section the TMA blocks the sections shred.  It's really hard to get a nice ribbon or even a nice section.  I don't know what I am doing wrong.  Has anyone had problems cutting TMAs before?  Any solutions?  We are using the Arraymold instrument.
