What are optimum storage conditions for a custom gene?

IDT ships custom gene dry unless otherwise requested. While dry they should be stable almost indefinitely.

After resuspending in a high-quality, molecular-grade water or buffer, pH 7.5–8.0, you should store the DNA at –20°C, and if necessary, aliquot to avoid more than 2 or 3 freeze-thaw cycles.
