Custom siRNA Oligos

Custom siRNA Oligos

Quality control

All oligos undergo vigorous monitoring and stringent quality control. Produced under ISO 9001:2015 quality standard system. Products are quantified by spectrophotometer

Purification

HPLC. siRNA content >97%

Modification

3′ and 5′ end Biotin, FAM and Phosphorate

Length

19-23 bases/each dsRNA

Product style

Single-stranded aliquots. Annealing dsRNA aliquots.

Storage and stability

Although oligonucleotides are stable in solution at 4 C for up to 2 weeks, TAG Copenhagen recommends storage should be at -20 C. Repetitive freeze-thaw cycles should be avoided by storing as aliquots. Storing at concentrations above 20 mikroM is recommended. TAG Copenhagen guarantees its oligonucleotides for 6 months, stored under the above conditions.

Technical Data Sheet

Oligonucleotides are delivered with an oligonucleotide technical data sheet, which includes oligo name, sequence, concentration precise quantity in OD and nmols, Tm, MW, size, extinction coefficient and purification data.

Personal service

Aliquot products according to customer’s request.

Shipment

Shipped by express delivery in 1,5 ml transparent tubes in dried powder.

Chemically Modified siRNA Oligos

The biggest challenge of RNAi technology is the siRNA stability problem. TAG Copenhagen modified siRNA can obtain the best result.

  • Highly effective gene knockdown
  • High stability – in blood serum and culture medium
  • Greatest limit reducing side-effect
  • Longer response time

Concern

siRNA Degradation

Long-lasting effect

In vivo Activity

siRNA

TAG Copenhagen modified siRNA results in greater longevity in cell culture and stability in cell culture and in serum, enhancing the ability for this to be used for in vivo application.

TAG Copenhagen chemical modified siRNA has much more extension effective time than Standard siRNA.

TAG Copenhagen chemical modified siRNA has high stability in most in vivo application.

Standard siRNA

Umodified RNA quickly degrades in cell culture and is unlikely to ahve extended longevity in cell and culture and be effective in most in vivo application

Short time, most of all is about one week or so.

Standard siRNA haas lower stability and not suitable in vivo application.
