By using Invitrogen’s award winning BLOCK-iT RNAi Designer, you can create custom Stealth RNAi siRNA sequences for any organism. The BLOCK-iT RNAi Designer can design custom Stealth RNAi siRNA duplexes based on a cDNA sequence, GenBank accession number, or by converting your existing siRNA to a Stealth RNAi siRNA duplex.

Custom Stealth RNAi siRNA duplexes provide

  • All of the advantages of Stealth RNAi siRNA chemistry
  • Custom design of Stealth RNAi siRNA duplexes and controls for any organism
  • The ability to convert your existing siRNA sequences to Stealth RNAi siRNA

Custom design gives more flexibility

If you need a synthetic RNAi duplex to study an organism other than human, mouse or rat, Custom Stealth RNAi siRNA is the perfect option.  If you need more than 3 duplexes for your target gene, then Custom Stealth RNAi siRNA can help design additional sequences not found in the Stealth Select 3 Sets. The BLOCK-iT RNAi designer can also help design scrambled controls for each of your Custom Stealth RNAi siRNA sequences.
