MSIA-SRM ASSAY FOR BIOMARKER ANALYSIS

摘要

The present disclosure provides assays, methods and signature peptides for the identification and quantification of biomarkers in a sample. In particular, the present disclosure relates to the development of mass spectrometric immunoassays with selected reaction monitoring mass spectrometry (MSIA-SRM MS) platforms for biomarker analysis. The MSIA-SRM MS platform may specifically be used for discriminating between particular variants of one or more biomarkers. In addition, the MSIA-SRM platform of the present invention may identify and/or quantify a biomarker and/or its variants present at low abundance in a sample.
