Custom siRNA Modification Services
Custom Options Beyond the Norm
Looking for a special siRNA modification or synthesis scale that wasn’t offered on our main RNAi page?
Top-Notch Service. Premium Quality.
Our highly trained scientists can custom-synthesize almost any siRNA you can dream up. Whether you need one siRNA or thousands, your project receives meticulous handling and QC throughout the process.
Only Invitrogen can provide both Stealth RNAi™ siRNA and Silencer® Select siRNA, which offer unparalleled silencing efficiency and specificity. Use either of these powerful technologies as the basis for your custom project, or let us modify standard 21-mer siRNAs for you.
