What is the fidelity of your Ultramer® Oligonucleotide synthesis?

Standard DNA oligos have a coupling efficiency of 99.2%. Ultramer oligos have a 99.5% coupling efficiency. This increase results in higher fidelity synthesis. With both syntheses, purification may be recommended for longer oligos based on your specific application. For further information regarding Ultramer oligos, please see our Ultramer Oligos Catalog Page at www.idtdna.com.
