To order Stealth RNAi™ siRNA molecules with proprietary chemical modifications based on existing siRNA (19 nt), enter the target gene GenBank accession number or the nucleotide sequence, choose database for Blast, enter the 19 nt siRNA sequence and click 'Submit'.

Note: The siRNA to Stealth RNAi™ siRNA conversion typically results in functional RNAi molecules. However, for the most effective Stealth RNAi™ siRNA molecules, design your Stealth RNAi™ siRNA de novo using the Stealth RNAi™ siRNA design option.
