Hi Angelina,
We were having the same problem with frozen mouse aortas. I was cutting at 5ums
onto superfrost slides and was losing about half of my sections. I ended up
swapping to superfrost plus ultra, plus I bake the slides in the histology oven
at 60 degress celcius for 10 minutes and now I nearly never lose a section -
the only time I do is when I have done a lazy job of cutting and have collected
a section with a fold in it.
Good luck!
