Custom-made psiRNA

Choose your siRNA sequence
You can either send us your siRNA sequence or, using the siRNA Wizard software, InvivoGen will select the best candidate siRNA sequence for your target gene.

Although the siRNAWizard software can facilitate the selection of functional shRNAs, there is no guarantee that the resulting shRNA will be effective enough for your experiment. Thus it is usually recommended to select 3-5 candidate shRNAs.
Furthermore, most journal article reviewers require that gene silencing results be confirmed with a second effective siRNA to a target before an article is accepted for publication.

Orders of multiple psiRNA plasmids targeting the same gene will be eligible for a volume discount.

- psiRNA-h7SK
- psiRNA-DUO

Choose your selectable marker
psiRNA plasmids are available with various selectable markers that confer antibiotic resistance in both E. coli and mammalian cells:
- Blasticidin
- Hygromycin
- Kanamycin / G418
- Zeocin™
- GFP::Zeo

Construction of custom-made psiRNA plasmids includes the following:
- Selection of the siRNA sequence for the target gene
- Synthesis of the siRNA insert oligonucleotides
- Cloning of the annealed oligonucleotides in psiRNA
- Sequencing of the siRNA insert

Custom-made psiRNA are provided as 20 µg of lyophilized DNA. They can also be provided as a kit that contains in addition:
- 20 µg of a control psiRNA plasmid (psiRNA-EGFP or psiRNA-Luc)
- 1 vial of LyoComp GT116
- 4 pouches of the corresponding Fast-Media©
