Specifications of siRNA Oligos


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. Quantity is systematically validated by UV absorbance at 260 nm.
Purification Fully deprotected and desalted
Purified by RP-HPLC upon request
Delivered Quantity 2 OD (~10 nmol), 5 OD (~25 nmol), 10 OD (~50 nmol)
Length 19 to 45 mers
Bases RNA
DNA
2'OMe
Backbone Phosphodiester bond
Labels and modifications Amine, biotin, Cy-dyes, fluorescein, phosphate. Other labels available upon request
Format Simplex siRNAs are delivered dry.
Duplex siRNA oligos are delivered dry or liquid
Storage and stability Although oligonucleotides are stable in solution at 4°C for up to 2 weeks, Sigma recommends 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. Sigma guarantees its oligonucleotides for six months, when stored under the above conditions.
Shipment Shipped by express delivery, dry or liquid in individual, transparent tubes

Technical Data
Sheet
Oligonucleotides are delivered with an Oligonucleotide Technical Data Sheet, which includes oligonucleotide name, sequence, concentration, precise quantity in OD and nmols, Tm, MW, size, extinction coefficient and purification data. Additional gel images are provided for duplex confirmation upon request.
