How can I order my oligos?
We generally recommend to order online via our Ecom system. This is the most convenient and secure way and you benefit from several online features like order tracking, order history and archived documents.
If you are not able to order online, please use our order forms from our website and send it via email to firstname.lastname@example.org.
Can I order by uploading an excel file?
Yes you can.
Just use our excel templates which can be downloaded from the respective product order pages. Save your excel file as .xls or .xlsx on your personal computer. The name of the oligo is restricted to 25 characters. No further format rules have to be considered.
How can I order degenerated/wobble bases?
A mixture of bases is commonly known as a wobble base. Please find the universal nomenclature (IUPC code) in the following table. Just include the respective character in the oligo sequence.
A wobble is generated by equal amounts of different phosphoramidites in one coupling reaction during synthesis. Not all nucleosides are equally incorporated during synthesis; it is not uncommon to observe a slight bias at the wobble position in the final product.
In addition to standard wobbles (i.e. Y (CT) 50:50) you can also order wobbles in a defined ratio (i.e. CT 30:70) by choosing "wobble defined ratio" in the modifications drop down. Please define your requested ratio in the production comment during checkout.
How can I order oligos with phosphorothioate bonds (PTO)?
Phosphorothioate (PTO) oligonucleotides "PTO oligos" can be ordered as Custom DNA Oligo. PTO bounds should be indicated by an asterix "*".
Can I order modified RNA?
Yes. Please use the Custom RNA Oligo order form within your Ecom account. 3' and 5' modifications may be selected.
How do I order chimeric oligos?
Please select the O-Methyl-RNA /Chimerics order page in our Ecom system.
To define the sequence:
- DNA = ACGT
- RNA = (ACGU)
- PTO = A*C*(G*U)
How can I cancel or amend an order?
It is possible to change or cancel your oligonucleotide order within 30 minutes after your order has been sent.
If you have ordered online, you can cancel your order by yourself using the link "cancel icon" under "my orders".
