siDirectPlus
Efficient and Secure siRNA Design Tool– Now Available Offline!
siDirectPlus 2024 Edition Now Available! ・ A new feature has been added: allows gene extraction with sequences complementary to the seed region in the 3'-UTR region as off-target candidate genes! ・ Now you can input gene sequences by referencing the bundled database enabling completely offline use! |
Overview
siDirect is a sequence design tool for siRNA required to induce RNAi in mammalian cells. A major advantage of siDirect is its ability to design sequences that suppress off-target effects. Since the first version was released in 2004, researchers have been able to access the website to design siRNAs.
siDirectPlus is the offline version of siDirect. Sequence information explored in drug discovery is highly confidential data that cannot be handled online. Therefore, we recommend using siDirect Plus, which offers equivalent functionality offline. Off-target searches can be integrated with the GGGenome high-speed base search engine; an offline package for this is also available.
