Ordering:
Please fill in the order form here and send it to: order@genepharma.com. Our staff will confirm with you asap.
We synthesize up to 4 pairs of siRNA oligos for each specific gene target, so that you almost always have at least one pair showing 70% down regulation or more. We guarantee at least one construct that has at least up to 50% transfection efficiency, and at least 70% inhibition efficiency (qPCR). If not, we will synthesize 4 new siRNA sequences for free.
*If your order is over $1000 USD, delivery is free. Payment terms are net 30 (due in 30 days upon invoice receipt). Wire transfer or credit card into our USD account are accepted methods of payment.
Support:
For technical questions, email support@genepharma.com. For questions relating to your order, email bd@genepharma.com.
Quality Control:
All our siRNA oligos undergo vigorous process monitoring and strict quality control. Length and labeling are systematically controlled by PAGE or mass spectrometry analysis. The quantity is systematically validated by UV absorbance at 260 nm.
Specifications of siRNA Oligos:
- Purification: Fully deprotected and desalted.
- Purified by PAGE or RP-HPLC upon request.
- Length: 19 to 23 bp/strand.
- Bases: RNA (A, C, G or U); DNA (A, C, G or T).
- Backbone: Phosphodiester bond.
- Labels and modifications: Fluorescein, biotin and phosphate: 3' or 5'end.
- Other labels available upon request.
- Format: Single-strand RNA oligos are delivered in dry form.
Storage and stability
Although oligonucleotides are stable in solution at 4°C for up to 2 weeks, we recommend storage should be at -20°C. Repetitive freeze-thaw cycles should be avoided by storing as aliquots. For long-term storage, siRNA oligos should be dried.
Oligonucleotides with fluorescent labels should be protected from light. We give a 6-month guarantee on our oligonucleotides, when stored under the above conditions.
Shipment:
Shipped by express delivery, dry in individual, transparent tubes.
Technical Data Sheet:
Oligonucleotides are delivered with a Technical Data Sheet, which includes oligonucleotide name, sequence, concentration, size and purification method.
