ULTRA-SENSITIVE DETECTION SYSTEMS USING MULTIDIMENSION SIGNALS

摘要

Disclosed are compositions and methods for sensitive detection of one or multiple analytes. In general, the methods involve the use of special label components, referred to as multidimension signals. In the disclosed methods, analysis of multidimension signals can result in one or more predetermined patterns that serve to indicate whether a further level of analysis can or should be performed and/or which portion(s) of the analyzed material can or should be analyzed in a further level of analysis. In some forms, isobaric a nd non-isobaric elements can be used together in the same assay or assay system . Isobaric and non-isobaric multidimension signals used together can generate one or more predetermined patterns during analysis. The pattern generated in this first level of analysis indicates whether the second level of analysis should be performed. The second level of analysis can involve distinguishing the isobaric multidimension signals.
