Diluent: Anhydrous Acetonitrile Add fresh diluent to product vial to recommended concentration and swirl vial occasionally over several minutes until product is completely dissolved. (Some oils may require between 5 and 10 minutes.) Use care to maintain anhydrous conditions. In case of transfer to alternate vial type, ensure recipient vial has been pre-dried. For more information, see http://www.glenres.com/Technical/TB_ABITransfer.pdf.
Coupling: 12-15 minute coupling time. To maintain label yield, carry out the synthesis DMT-On.
Deprotection: To maintain label yield as a 5' modifier, cleave and deprotect as required by nucleobases and then remove the DMT group. Alternatively, treat column with 10% diethylamine in acetonitrile for 2 minutes at room temperature (2x) to remove cyanoethyl protecting groups and rinse with ACN. At this point, the DMT group may be safely removed without loss of label during deprotection.
The table below shows pack size data and, for solutions, dilutions and approximate couplings based on normal priming procedures. Please link for more detailed usage information with the various synthesizers.
