What are the recommended storage conditions (pH, temperature, solvent, time) for DNA oligonucleotides? Dye labeled oligos? RNA oligos?
ASI recommends storage at -20 degrees, lyophilized. If not dried, than storage in ammonium hydroxide at -20 is acceptable. DNA oligos can be stored almost indefinitely in these conditions. Dye labelled oligos should be stored dry or in ammonium hydroxide at -20, for 1 month. RNA oligos can be stored dry or in ammonium hydroxide for 2 months.
