I left my oligonucleotides sitting on the lab bench over the weekend. Are they still ok to use?

Dry oligonucleotides are quite stable at room temperature and not likely to degrade over the short term. We recommend they be moved into cold storage upon delivery or as soon as possible. Oligonucleotides in solution at high concentration can be stored refrigerated for a few days or even one week. At lower concentrations, oligonucleotides are more susceptible to degradation. In all situations, Dual-labeled BHQ® probes should be protected from light to avoid photo-bleaching.
