DNA & RNA Oligonucleotides FAQs


How long are oligos stable and how should I store them?


The following stabilities apply under appropriate storage conditions i.e., light protected in a tightly closed container, no freeze/thaw-cycles:

Oligo Type Temperature Dissolved (H2O) Lyophilised / Dry Comment

Unmodified Oligonucleoties
Ambient
(+15°C to +25°C)
1 month 36 months  
Chilled
(+2°C to +8°C)
6 months 36 months  
Frozen
(- 22°C to - 18°C)
36 months 36 months  
Modified Oligonucleoties Frozen
(- 22°C to - 18°C)
  12 months Stability can vary depending on modification type
