We are an EN ISO 9001 and 13485 certified EU-located company manufacturing custom DNA oligos. We have been synthesizing custom DNA oligonucleotides since 1995. Every year our custom oligo synthesis services produce dozens of thousands of oligos in many categories: unmodified oligos, variously modified oligos, oligos with various types of purifications and for various purposes (biological techniques based mostly on PCR, NGS, biophysical studies etc.). We produce real-time PCR probes as well.
The know-how we acquired in custom DNA oligo synthesis during more than 25 years is implemented into the development of other products, especially CE IVD kits and Life Sciences products.
Our typical partners are end-users of the custom DNA oligos (customers mostly in CZ and SK), business partners and distributors. We are looking for business partners and/or distributors worldwide who can fit the portfolio of our products, either the whole or a part of it, into their sales strategy.
dU Deoxyuridine is usually introduced to the oligonucleotide DNA instead of deoxythimine. May be attached anywhere within the oligonucleotide sequence.
7-Deaza-8-aza-dG It is used to study oligonucleotide activity changes following alteration of the main structural component. 7-Deaza-8-aza-dG may be attached anywhere within the oligonucleotide sequence except for the 3' end.
7-Deaza-dA It is used to study oligonucleotide activity changes following alteration of the main structural component. 7-Deaza-dA may be attached anywhere within the oligonucleotide sequence except for the 3' end.
5-I-dU May be attached anywhere within the oligonucleotide sequence except for the 3' end. It is used for crystallographic studies of oligonucleotide structures. 5-I-dU is photolabile, the feature which is utilized in cross-linking studies investigating protein-DNA complex structures.
5-Br-dU May be attached anywhere within the oligonucleotide sequence except for the 3' end. It is used for crystallographic studies of oligonucleotide structures. 5-Br-dC is photolabile, the feature which is utilized in cross-linking studies investigating protein-DNA complex structures.
8-Oxo-dG May be attached anywhere within the oligonucleotide sequence except for the 3' end. It is used for structural and activity studies concerning oligonucleotides carrying an 8-oxo mutation. This naturally occurs when DNA is exposed to oxidative agents or ionizing radiation.
5-Me-dC Increases duplex stability and is suitable for antisense applications. May be attached anywhere within the oligonucleotide sequence.
Hexynyl It is used for conjugations based on the click chemistry principle. Hexynyl may be attached to the 5' end of the oligonucleotide.
C8-Alkyne-dC It is used for conjugations based on the click chemistry principle. C8-Alkyne-dC may be attached anywhere within the oligonucleotide sequence except for the 3' end.
C8-Alkyne-dT It is used for conjugations based on the click chemistry principle. C8-Alkyne-dT may be attached anywhere within the oligonucleotide sequence except for the 3' end.
Phosphorothioates Phosphorothioates contain the exchange of one oxygen in the phosphate bond with sulfur. By exchanging oxygen for sulfur, the resistance of the oligonucleotide to nucleases increases.
