siRNA Technology 

siRNAs are powerful tools for gene silencing and can be delivered to the target cell or host via a variety of methods including ready-to-use lentivirus, AAV, adenovirus, or direct transfection of DNA plasmids or double stranded RNA (dsRNA). Our unique convergent dual promoter system avoids the need to design hair-pin loop shRNA structures, streamlining cloning and knockdown of the target gene.

We offer a comprehensive collection of human, mouse, and rat siRNAs pre-designed for knockdown of your gene of interest. Can't find what you're looking for? We can generate Custom siRNA vectors and viruses tailored to your experiment.
"The lentivirus (Cat. No. iV059988a) I received is working really well with my primary bone marrow stem cells. The transfection rate is nearly 70% in five days. Great product, I would like to continue to using your products.”
