Chemical Phosphorylation Reagent II

Chemical Phosphorylation Reagent (CPR II) contains a DMT group which can be left on the oligonucleotide and used for rapid purification of oligonucleotide 5'-phosphates by the popular DMTr-on technique, which employs disposable RP cartridges or “Trityl-on” RP HPLC purification. The DMTr group is removed with aqueous acid (e.g., 2%TFA in the case of Cartridge Purification) and the remaining linker is then eliminated after brief treatment with aqueous ammonium hydroxide (12 -15% ammonium hydroxide at room temperature for 15 minutes) to yield the 5'-phosphate.
