What is the storage condition you recommend for 10uM working solution of oligos and probes?

Ideal storage for resuspended primers and probes is -20°C.  However, please note that IDT recommends end-users to store their oligos in the dry, lyopholized state at -20°C until the first day of use. 

We recommend resuspending your primers in a pH-controlled buffer, this will keep the pH in the more optimal pH range of 7.5-8.0; oligos degrade faster if the pH deviates from this pH range, especially lower pH levels.  We also recommend that you make working aliquots from your oligos and that each aliquote undergoes no more than 5 freeze/thaw cycles.  If you follow these optimal storage conditions your oligos should last at least 6 months at -20°C.
