Custom siRNA

Easy online ordering of standard, Dharmacon enhanced, and modified siRNAs. Ability to incorporate mismatches and internal modifications except for positions where restricted by Dharmacon patented modifications do not allow for changes in base content.

All oligos made by Dharmacon are verified for quality using mass spectrometry. This data is available on request for a fee. Additionally, we can provide UHPLC data on request as an additional service. Contact Scientific Support for more information.
