Uncovering Key Information About Disease Mechanisms Using Protein Quantitative Mass Spectrometry

Proteins are important functional molecules in living organisms. This makes protein quantitative mass spectrometry important and widely applicable in revealing disease mechanisms. Through this technology, key information can be obtained to study the molecular mechanisms of disease occurrence and development. At the same time, understanding the quantitative changes in proteins during disease processes is also of great significance for finding new therapeutic targets and personalized medicine.

 

Proteomics is a discipline that studies the composition, structure, function, and interaction of all proteins in organisms. By comprehensively analyzing the composition and changes of protein samples, the complexity of the biological system is revealed. Protein quantitative mass spectrometry is a method based on mass spectrometry technology, which realizes the quantitative analysis of proteins by measuring the mass spectrometry signal of specific peptide segments in protein samples. Common methods include labeling and non-labeling methods, such as isotope labeling and Multiple Reaction Monitoring (MRM).
