Your Partner for Custom Oligonucleotides
TAG Copenhagen specializes in high-quality custom oligos, primers, and dual-labeled probes tailored to the needs of academia and the pharmaceutical industry. With advanced oligonucleotide synthesis and rigorous LC/MS quality control, we ensure precision and reliability for diverse applications, from research to diagnostics.
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
