Dmt on purification

WebFor example, DMT-on purification, e.g., Glen-Pak RNA, has become increasingly popular for the purification of RNA oligos, especially siRNA, so all deprotection schemes must leave the DMT group intact to allow purification to take place. Cleavage. For RNA oligos we do not routinely use a separate cleavage step. Webpurification step becomes more difficult as the oligonucleotide length increases. Trityl-on purification enhances the selectivity between the full length sequence and the truncated failures. Solid phase extraction (SPE) tubes provide a low cost method ...
