Re: Re-Immuno control sections
Another factor to bear in mind when cutting large volumes of control slides
is that the site of interest might be only localised and that it might
disappear from the section. This is not of crucial importance when using
normal tissue, but is when using tumour blocks.
Just my 2 cents worth!
