Re: [Histonet] Re: Superfrost slides-Histonet question
You are very welcome! It was a pleasure to visit with you at Phoenix NSH
S/C. Keep up the good work creating those clever tools you have for
cryosectioning!!! Your waffle weave "grid" (square and rectangular) metal
disks are superbly designed for holding frozen tissue blocks - the BEST!!!
especially for undecalcified bone cryosectioning and they fit in my 1850's,
all three of them!
