[Histonet] Re: Isopropanol in paraffin processing
Thank you Professor Smith for coming to my rescue and agreeing that
isopropanol and melted paraffin wax are mutually soluble at least to some
i have not tested the exact proportions of each that will dissolve
together but I have used isopropanol to process small biopsies without the
use of a clearing agent.
The advantage of this is vastly improved staining.
The downside of the technique is that isopropanol is poorer at removing fat
than ethanol followed by xylene and therefore tissue blocks with a higher
fat content may not infiltrate with wax properly, resulting in poor
