[Nhcoll-l] HistoChoice

Tue Feb 9 04:58:41 EST 2016

Hi Simon!

I was supposing that this would be a salt based fixative, but it is not 
possible to get any information on its composition. Judging fromt he bad 
experiences with salt based "fixatives" (e.g. DMSO), I am wondering if 
HistoChoice fixed specimens would remain stable in the long run, because 
it surely would be difficult to re-fix them ... even after rinsing.

Do you have any thoughts on this ?

Have a nice day,
Dirk
