I am trying to store my slides carrying stained DNA using fluorescent dye (Hoechst DNA staining) for a long period of time. how can I do it?,...Do you have any advice?
I agree with using an anti-fade and sealing the coverslip (nail polish). Keeping the slides in the dark as suggested is advisable and you can also store them at 4C (never frozen) cold room for longer storage.
slides and mounting medium should be stored at 2-8C and also in the dark with a perfect sealing. In this situation could be stable for about few months.
