2021-06-27 19:50 In order to assess the biological function of proteins for understanding signaling mechanisms within cells as well as specific biomarkers to disease, it is vital to study the difference of proteome under different experimental conditions. The new emerging mass spectrometry-based quantitative proteomics provides a powerful tool to quantitatively and systematically assess quantitative differences in protein profiles of distinct samples and increasingly defines as a significant component of biomedical and clinical research.
