METHODS FOR ANALYZING A TISSUE SAMPLE

摘要

The invention generally relates to methods for analyzing a tissue sample. In certain aspects, the invention provides methods that involve obtaining a tissue sample including an unsaturated compound, conducting a radical reaction on the tissue sample that targets a carbon- carbon double bond within the unsaturated compound to thereby produce a plurality of compound isomers, subjecting the plurality of compound isomers to mass spectrometry analysis to identify a location of the carbon-carbon double bond within the unsaturated compound, and quantifying the plurality of compound isomers in order to distinguish normal tissue from diseased tissue.
