I have PCR products stored at -20 degrees (Celsius) that are tagged with FAM dye. How long can these be kept before the fluorescent signal diminishes?
As long as the FAM is protected from light, it should be stable for a very long time.
Thank you for your answer, Adam!
If they are constituted (water or TE) and kept at -20C, they are good for up to 18 months.
If they are dry, up to ~24 months.
