Yes. If you can provide the aptamer sequence(s), you can order directly from the IDT website. To order online choose “Main Menu” from the “Order” drop-down menu. Click on “Custom DNA Oligos,” or if your sequence contains RNA bases, “Custom RNA Oligos.” Enter your desired scale, sequence, and purification.
If you are ordering aptamers with a fixed sequence, IDT recommends HPLC or PAGE purification. For aptamer libraries containing random bases, IDT recommends standard desalt.
