Order Multiple Single-strand DNAs

Order multiple DNA only oligos with same design criteria in one convenient interface; simply enter your sequences and select criteria that will apply to all DNA oligos. This page is for ordering custom DNA. Order single-strand RNA and DNA-RNA chimeras from here.

Ordering Guidelines

Synthesis scale

Maximum DNA length for online ordering1

0.05 µmol


1.0 µmol


1For DNA inquires with scales other than those listed please contact Technical Support

Please Note:

Synthesis scale does not represent final yield. Longer lengths, modifications, and purification will result in decreased DNA yields. Oligos at 0.05 µmol scale with HPLC purification, particularly if longer than 80 bases, will result in a low total nmol yield.
