Silantes provides an enzymatic synthesis service for DNA and RNA labelled with the stable isotopes 2H, 13C and 15N and combinations thereof. This enzymatic approach allows uniform labelling of DNA and RNA fragments. For a nucleoside-specific labelling, please see our custom chemical oligo-synthesis service.
The RNA synthesis is performed in the T7 RNA-polymerase system. The reaction is started by adding the T7 RNA-polymerase enzyme to a buffered mixture containing
The DNA synthesis is performed in a mixture containing
The performance of the reactions are monitored and analyzed by ion-exchange chromatography. The figures show elution profiles of a r14mer RNA fragment after 2 h (left) and a d15mer DNA fragment after 6 h (right).

The amount of the products is counted in optical units and re-calculated into nmol using a special coefficient.

Based on this information, we conduct a feasibility study for your project priced at 620 €. If the project is feasible and the synthesis service is ordered, the costs for the feasibility study get reimbursed.
The delivery time is 6 weeks.
With our custom oligo synthesis service, we conduced a great number of prestigious projects to success. One example is the following synthesis of an E.coli promoter sequence:
Isotopic labelling: 13C, 15N (uniformly, >98 %)
Quantity: 1 mg
This project was successfully realized at a price of 2380 €.
