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.

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