Application and Development of MRM Technology in Protein Analysis

As the importance of proteins in biomedical research and biopharmaceutical development becomes increasingly prominent, the demand for protein analysis is also becoming more urgent. In the field of proteomics research, one widely applied technique that has garnered attention is MRM (Multiple Reaction Monitoring) technology. This article will provide a detailed introduction to MRM technology and discuss its applications and developments in protein analysis.

1. Principles of MRM Technology

MRM technology is a quantitative method based on mass spectrometry, used to detect and quantify specific peptides of target proteins. It is based on the selectivity and sensitivity of the mass spectrometer towards peptides, achieving quantification of target proteins by selecting and monitoring specific transition reactions. MRM technology typically involves two stages: precursor ion selection and selected reaction monitoring. By optimizing the parameter settings for these two stages, the accuracy and sensitivity of protein quantification can be improved.
