Physical & Dilution Data

Dilution volumes (in ml) are for 0.1M solutions in dry acetonitrile (4050). Adjust accordingly for other concentrations. For µmol pack sizes, products should be diluted as 100µmol/ml to achieve 0.1M, regardless of molecular weight.

ETT, BTT or DCI can be used as activators. A coupling time of 6min (360s) is recommended.


No changes are required from standard methods.

Cleavage & Deprotection

Standard oligonucleotide deprotection conditions can be applied when deprotecting an oligo containing these modifications. In general, AMA at 65ºC for 10min is used, employing dmf-G and Ac-C in the sequence.

Storage & Stability

Store in a freezer below -10°C. Diluted samples are freshly prepared and used within 24h.
