    摘要: A computer-implemented method for confirming the nucleotide sequence of an oligonucleotide is provided. In certain embodiments, the method comprises: a) inputting the nucleotide sequence of an oligonucleotide; b) executing an algorithm that provides the predicted molecular formulas of fragments of the oligonucleotide; c) comparing the predicted m/z values of the predicted molecular formulas to experimentally-obtained m/z values obtained by analysis of the oligonucleotide by tandem mass spectrometry to determine if the predicted masses correspond with the experimentally-obtained masses. The method may be used, for example, to confirm the identity of a. oligonucleotide after it is synthesized, i.e., to confirm that it has the expected sequence.

    摘要: A method and compositions for sulfurizing at least one phosphite or thiophosphite linkage in an oligonucleotide. The methods employ a phenylacetyl disulfide reagent (known as PADS), phenylthioacetic acid (PTAA) in the presence or absence or N-alkyl imidazole in industrially preferred solvents or solvents that are derived from renewable resources. The use of PTAA eliminates the need to “age” the PADS solution prior to its use in sulfurization reactions.
