License for click chemistry has acquired an extensive global license from baseclick to perform azide-alkyne click reactions on nucleic acids. This license includes the synthesis of modified oligos by copper-catalysed click chemistry, as well as the allocation of clickable oligos, followed by realisation of click reactions for research purposes only. In particular, the technology protected by baseclick for internal click modification of nucleic acids on heterocyclic bases (via 5-alkyne pyrimidines) is also included in the agreement. offers now the entire portfolio of click-modified oligos worldwide.
Take advantage of state-of-the-art synthesis technology:
Oligonucleotides with all popular modifications at reasonable prices and with a reliable quality. Oligos for PCR, short, unmodified and quickly delivered are offered as well as high quality RNA oligos, probes for qPCR and FISH or reliable cloning oligos of (nearly) any length.

Oligos with SNAP and CLIP tag protein ligands
Benzylguanine and Benzylcytosine-labelled oligonucleotides as substrate for the protein tags SNAP and CLIP tag.

Both protein tags allow the visualisation of complex, cellular processes:
- protein-protein interactions
- protein localisation
- protein function analyses
