Oligonucleotides are relatively stable molecules and be stored for up to a maximum of 2 years under optimum handling and storage conditions. The exact storage time depends on the storage conditions.
Storage temperature | Storage condition | Approximate storage time at which Oligonucleotides will remain stable |
Freezer at -20° | Dry or in water or TE buffer solution | 2 years |
Refrigerator at 4°C or lower temperature | Dry or in water or TE buffer solution | 1 year |
Room temperature | Dry or in TE buffer solution | 3-6 months |
Higher temperatures such as when stored in shipping or storage warehouse under non-temperature controlled conditions | Dry or in TE buffer solution | 1-2 months |
The shelf lives mentioned above are estimates only. Various other factors may affect the stability of Oligonucleotides.
