*** IMPORTANT NOTICE ****
The CCIB DNA Core has discontinued its Oligo Synthesis services effective July 1, 2021.
DNA Synthesis: Custom Oligonucleotides
Take advantage of our experience! Our qualified DNA Synthesis team has been operating for more than 18 years and can fully leverage its special expertise in the synthesis of custom DNA oligonucleotides. We are employing a synthesizer from a leading manufacturer, we have optimized the synthesis cycles, we use high concentrations of building blocks, and we are working with high quality chemicals from selected suppliers. Our products are routinely used for in-house applications such as DNA sequencing, PCR, hybridization, cDNA synthesis, and in vitro mutagenesis.
We offer the following oligonucleotide synthesis service options:
Standard DNA Oligonucleotides
| Synthesis Scale | Oligonucleotide Length | Provider |
| 50 nmole | 3-75 bases | CCIB DNA Core |
| 200 nmole | 3-75 bases | CCIB DNA Core |
| 100 nmole | 76-90 bases | outsourced |
| 250 nmole | 91-100 bases | outsourced |
| For > 100 bases, please inquire! | ||
Please note:
To fulfill the increasing demand for our DNA synthesis services
while maintaining our rapid turnaround for our standard products,
we are providing very long oligonucleotides
(including PAGE purification option; see
here) through our partnership with IDT. All oligonucleotides are discounted from IDT’s list price and receive free shipping to our core facility.
Modified DNA Oligonucleotides
| Modification | Synthesis Scale | Oligonucleotide Length |
| 5' Biotin | 50 nmole, 200 nmole | 3-75 bases |
| 5' 6FAM | 50 nmole, 200 nmole | 3-75 bases |
| 5' HEX | 50 nmole, 200 nmole | 3-75 bases |
| 5' Phosphorylation | 50 nmole, 200 nmole | 3-75 bases |
| For other modifications, please inquire! | ||
Degenerate DNA Oligonucleotides
Our team offers the synthesis of DNA oligonucleotides with equimolar mixtures of two or more different bases at a given position within the sequence. Synthesis scales of 50 nmole and 200 nmole are available. No extra charges apply.
