METHODS, MIXTURES, KITS AND COMPOSITIONS PERTAINING TO ANALYTE DETERMINATION

摘要

This invention pertains to methods, mixtures, kits and/or compositions for t he determination of analytes by mass analysis using unique labeling reagents or sets of unique labeling reagents. The labeling reagents can be isomeric or isobaric and can be used to produce mixtures suitable for multiplex analysis of the labeled analytes.
