Hi Sharon, Donald & Bonnie who have thus far answered my mail

Regarding the section adherence of my sections  - the normal muscle controls
stuck beautifully, its just the dystrophy ones - I guess it could have been
a bad batch of silane slides, but I'm still looking for answers.....

Thanks
Louise

I would try the charged slides, especially with frozen sectioning.
Take care
