I have used Mowiol (essentially Polyvynyl alcohol) as a mounting agent.
Only drawback is it take a while to dry out. A drop on a slide with the
(rinsed in PBS) coverslip inverted onto it is great for up to a week.
2.4g Mowiol (Hoechst) or Gelvatol/Gelutol (Monsanto), 6g Glycerol.
Stirr to mix.
Add 6ml water and leave for several hours at room temperature.
Add 12ml 0.2M (or 0.1M) Tris pH8.5, heat to 50C for 10 minutes with
Once dissolved clarify by centrifugation at 5000 x g for 15 minutes
Aliquot and store sealed at 4C (or may be frozen).
