How will my order be shipped?

We ship via FedEx Priority which guarantees receipt by 10:30 am the following business day to most locations within the US. Our oligonucleotides are packaged in microcentrifuge tubes as lyophilized solids. Oligos are most stable lyophilized; however, we can ship them in solution in water or buffer upon request (an additional charge may apply). Unless requested, all oligos are shipped at room temperature. They are stable at room temperature, but should be stored at –20°C upon arrival. Compounds in solution, with a dimethoxytrityl group must be shipped on dry ice to ensure stability of the trityl group. Please note: dye labeled oligos are light sensitive. All oligos are shipped in an inner reflective Mylar envelope to shield them from light. This envelope can be used for storage.
