How do I order siRNA oligos?

We offer traditional 21mer duplex RNAs as well as 27mer, Dicer-substrate RNAs (DsiRNAs), which engage the Dicer enzyme natural siRNA processing pathway.

If you know the sequence you want to order, you can order either from the Order tab at by selecting Main Menu>Custom RNA Oligos.

We also have a DsiRNA selection tool that can be accessed under "Gene Silencing" on the Products tab of our website.
