How stable is my oligo once I have resuspended it?
If sterile diluent is used to resuspend the oligo, it will be stable at 4°C for about a month. If stored frozen at -20°C or -70°C, it will remain stable for 2-3 months. Repeated freeze-thaw should be avoided, as it will denature the oligo. Avoid the use of distilled water, since solution pH may be as low as 4-5.
