The invention provides methods of identifying one or more nucleic acids in a sample. The nucleic acids, for example, expressed genes in a cell, can be identified by contacting the nucleic acids with oligonucleotides having detector tags, and selector tags to form tagged oligonucleotides. Each nucleic acid can be uniquely identified by mass-spectrophotometric analysis of the detector tag.
本发明提供了鉴定样品中一种或多种核酸的方法。核酸(例如细胞中表达的
基因)可通过与具有检测器标记和选择器标记的寡核苷酸接触形成标记寡核苷酸来识别。通过对检测器标签进行质量-分光光度分析,可以唯一识别每种核酸。
