Trityl

WebHowever, the trityl-on option is selected when purifying using an OPC cartridge or certain types of HPLC. After purification, trityl-on oligonucleotides must be detritylated manually. The 5' dimethoxytrityl (DMT) is readily cleaved by limited exposure to mild acidic conditions to minimize depurination. WebThe trityl cation generated during detritylation has an intense yellow/orange color, and it has been used to determine the end point of the detritylation reaction using spectrophotometric methods. Using this approach, the acid contact time can be minimized/controlled without affecting trityl removal.
