The chemical synthesis of DNA oligonucleotides (DNA Primers) has a long tradition at BioTeZ. For 20 years, we are dealing with technology to synthesize DNA sequences. As a research-intensive company, we have a fine grasp on our client’s requirements concerning oligos / primer in order to make experiments and applications successful and efficient.

Many satisfied customers rely on our oligos and use them for a broad spectrum of different applications.

Cursory overview about our services in this field:

• DNA-Oligonucleotides (unmodified and modifiziert, Wobble etc.)    
• Synthesis of Oligonucleotides in microplates   
• RNA-Oligonucleotides    
• siRNA-Oligonucleotides  
• Chimere Oligonucleotides  
• 5‘- and 3‘-modificated RNA-Oligonucleotides

BioTeZ service DNA Oligonucleotides contains:

·         Synthesis of unmodified DNA-oligonucleotides

·         Synthesis of Backbone modified oligonucleotides (Phosphorothioate, 2’-O-Methyl)

·         Synthesis of Wobbles, Insertation of dI, dU, 5-Me-dC et al.

·         Synthesis of a variety of modified oligonucleotides (single- and double-tagged)

·         Standard purification via desalination (Sephadex G25)

·         Optional purification via RP-cartridge and RP-HPLC

We are providing the following labels on 5’ and/or 3’ end:

Aminohexyl, biotin, digoxigenin, phosphate, FITC, TRITC, rhodamine, 6-Fam, Hex, Tet, Tamra, Rox, Joe, Cy5, Cy3, BHQ1, BHQ2, BHQ3, Dabcyl DNP. If the desired label is not listed, please contact our oligo-team. We can make almost anything whether the corresponding components are available.

We have a special experience in synthesis of long oligonucleotides up to a length of 150 bases. Oligos with more bases requires special arangement.

All oligos / primers will be lyophilized and shipped without extra charge. Express delivery is also possible.

Based on a 20-mer, you can expect the following delivered quantities:

Of course you will receive the total output of the synthesis without extra charge!

The synthesis of oligos takes just a few days, depending on the order volume.  Feel free to ask for the processing time.

Processing time (work days) plus shipping time:

1 day for unmodified oligos (if ordered until 12 a.m.)

2-3 days for oligos HPLC-purified

3-5 days for oligos labeled and HPLC-purified

If an order is very urgent, please contact the Oligo-Team.
