Oligos

Custom Oligos

TAG Copenhagen is a leading supplier of custom oligos, primers and dual labelled probes to the academic world as well as the pharmaceutical industry. We have a long tradition within custom oligos. We started our mass production of custom oligos in 1996 and at the same time we started to develop our own oligo synthesizers (OligoMaker), that today are sold to DNA synthesis labs around the world.TAG Copenhagen was the first company in Europe to mass-produce custom oligonucleotides as well as to introduce Quality Control by LC/MS of all oligonucleotides, that today has become a standard of many manufacturers of oligonucleotides.

Competitive pricing

Today, we are able to offer high quality products to competitive prices due to own developed highly efficient synthesizers combined with a continuous focus on process improvements for the manufacturing process.

Quality guarantee

TAG Copenhagen is ISO 9001:2015 and ISO 14001:2015. Each of our employees has a long track record in the production of oligonucleotides with special attention on traceability, maintenance and calibration programs, supplier evaluation, process control, lot release and independent quality control.

  • All oligos are quantified twice by uv spectrometry to obtain an accurate measure of yield (OD measurement)
  • Certificate of Analysis (CoA) follows all oligos
  • Reverse Phase Column and HPLC purified oligos (<80 mer) are quality controlled by LC/MS MassSpec; batchwise for Primer Desalted
