| 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. |
