The amount of time depends on the type of oligonucleotide you order. Small-scale, unmodified oligonucleotides can take as little as three days. If purification is requested, the oligonucleotides will take slightly longer to be shipped. A midscale order (50 mg – 10 g), will take approximately four weeks. Highly modified or conjugated oligonucleotides can also take longer. We always ship your oligonucleotides out as quickly as possible, but we refuse to sacrifice quality. Upon placing the order you will receive a confirmation email that typically includes an estimated shipping date. We will update you as soon as possible if there are any changes to the estimated shipping date.
