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.

Duplex stability
In order to increase the affinity and stability of a duplex DNA, there is a range of different modified bases to improve hybridisation:

- Minor Groove Binder (MGB)
- C-5 Propynyl-Pyrimidines (pdC, pdU)
- Aminoethyl-phenoxazine-deoxycytidine (AP-dC, (G-clamp))
- 5-Methyl-deoxycytidine (5-Me-dC)
- 2-Amino-deoxyadenosine (2-Amino-dA)
Antisense oligos with 2´-O-MOE modification
- increased stability to enzymatic degradation
- improved distribution in cell
- bind with greater affinity to complementary RNA

BMN quenchers from
In addition to this wide range of available quenchers, also offers excellent alternatives.
Our quencher set nearly covers the complete wavelength range of visible light:
BMN-Q460 (400-530 nm), BMN-Q535 (480-580 nm), BMN-Q590 (550-650 nm), BMN-Q620 (480-720 nm) and BMN-Q650 (550-720 nm)
PNA oligos
Molecules with high affinity and sequence selectivity
PNA is extremely stable and show notable hybridisation properties, so that it is interesting for many applications:

- Antisense/Antigene drugs
- SNP detection
- Microarrays and biosensors
