Simultaneous Monitoring of Multiple Transitions in Mass Spectrometric Analysis Improves Limit of Detection for Low Abundance Substances in Complex Biological Samples
Journal of Chromatography & Separation Techniques
In mass-spectrometry, simultaneous monitoring of several transitions enables increased assay specificity, but also can be used as a tool to improve the lower limit of quantification. In this report, we propose a new approach to low abundant analyte detection in complex samples. The method consists of collecting two and potentially more, different mass spectrometry transitions with further analysis of a product function. For example, C-peptide detection was evaluated with two transitionsdoi:10.4172/2157-7064.1000206 fatcat:6yv45vlfmjgwxjjk5ldrhcq7lm
