Multiple Reaction Monitoring Mass Spectrometry

Multiple Reaction Monitoring (MRM) is a mass spectrometry technique used for the precise and sensitive detection and quantitative analysis of target compounds. As a mode of mass spectrometry application, it is renowned for its high selectivity and sensitivity, enabling effective identification and quantification of specific analytes in complex biological samples. This technique is widely used in fields such as proteomics, metabolomics, and drug analysis. Its principle involves selectively monitoring characteristic ion pairs of target compounds through tandem mass spectrometry (MS/MS), typically including a precursor ion and one or more product ions. MRM mass spectrometry is particularly important in proteomics research, especially in biomarker validation, absolute quantification, and small molecule metabolite analysis, providing strong support. In proteomics research, it can be used to accurately detect low-abundance proteins and their modified forms. This is significant in clinical diagnosis, disease mechanism research, and drug development. For example, MRM can precisely measure the expression levels of certain disease-related proteins, helping identify potential biomarkers. Additionally, in the fields of drug metabolism and pharmacodynamics research, it enables high-throughput analysis of drugs and their metabolites. This analysis not only provides insights into the pharmacokinetics of drugs in the body but also helps researchers optimize drug dosages and administration regimens.

 

The high sensitivity of multiple reaction monitoring mass spectrometry originates from its selective ion filtering mechanism. In MRM mode, the mass spectrometer uses electrostatic and magnetic fields to precisely and selectively detect precursor and product ion pairs of target molecules. This process significantly reduces background noise and enhances the signal strength of target compounds. Especially when handling complex biological samples, it effectively eliminates interference, making experimental results more reliable and accurate.

 

Multiple reaction monitoring mass spectrometry shines not only in basic research but also as an indispensable tool in clinical applications. Its sensitivity, accuracy, and selectivity make it excel at detecting low-abundance clinical samples, such as in cancer diagnosis and treatment monitoring, where MRM can achieve accurate quantification of tumor markers. Furthermore, in personalized medicine, it can assist healthcare professionals in devising personalized treatment plans based on patients' metabolic characteristics.
