How to fix spheroids to avoid loss of FITC signal ?

11 February 2020 0 9K Report

Hello.

I treated the 3D spheroids with a molecule FITC-conjugate. After 5 days of colture, I would like to fix the spheroids to see the fluorescence at confocal microscopy.

Do you a method to fix them, without losing FITC-signal?

Thank you
