Our custom siRNA oligos are pre-annealed duplex and are purified by HPLC, which removes 100% of unpaired single chains. We provide low price and high quality. Researchers just need to dilute siRNA oligos into DEPC H2O.
Researchers can give us your own designed oligo pairs for synthesis. Or we can design and synthesize 3-4 various siRNA pairs for each target gene, which at least one pair is guaranteed to work. Researchers can use one pair alone or multiple pairs mixed. The inhibition efficiency could be enhanced by mixing multiple pairs as "siRNA Pool". Order online or use order form
Our SiRNA Characteristics
| Quality Control | siRNA oligo synthesis is completed in an ISO9000 certified facility; Products are precisely quantitated by spectrophotometer. |
| Purification | HPLC purification; siRNA concentration >97% |
| Labeling and Modification | Biotin, FAM or phosphorate labeling in 3 'and 5' end are available |
| Length | 19-23 bp/strand |
| Product Types | Annealed dsRNA duplex as lyophilized powder |
| Storage and Stability | Although siRNA oligos are stable in solution at 4°C for up to 2 weeks, it’s recommended to store siRNA solution at -20°C. Repetitive freezing and thaw should be avoided by aliquots. The recommended storage concentration is above 20 μM. The siRNA oligos stored under above conditions are stable for at least 6 months. The fluorescence-labeled siRNA oligos must be kept in dark. |
| Technology Data Sheet | Technical data sheet is delivered together with siRNA oligo, including oligo name, sequence, concentration, the precise number of OD and nmols, Tm, MW, size, extinction coefficient and purification type. |
| Personalized Service | Aliquot under customer's request; Free design support |
| Delivery | 1.5ml freezing tube package; express delivery |
