[Histonet] Problems with Leica 1850
Interesting, we have three 1850's and never have cutting concerns with
them. We cut snap frozen bovine skin (tough leathery type) innumerable
tissues from mouse, rat, hamster, decalcified and undecalcified bone,
thick 50 um brain and have sectioned human tissues without problems and
some exotic other things like biofilms.
Maybe it is more than just instrument problems and your cryosectioning
technics (blades, temperatures, etc) that needs reevaluation. If you use
low profile blades exclusively and have not tried high profile blades, you
should TRY the high profile, and try other brands of knife blades. Some
blades perform much better than others. Accuedge high profiles are just
as sharp as their low profile blades but much sturdier for cryomicrotomy.
