I have tissue treated with fluorescently labeled EVs. What is the best way to process the tissue for sectioning that can retain the fluorescence?
I have tried cryostat sectioning. But the tissue sections look dirty, not as good as paraffin-embedded sectioning. And paraffin-embedded sectioning needs to go through a harsh environment (high temperature, xylene) that diminishes/quenches the fluorescence.
Any suggestion here? Thanks
