What is quantitative proteomics?
Quantitative proteomics uses liquid-chromatography (LC)-based separation combined with high-resolution mass spectrometry (MS) to identify proteins from biological samples then quantify relative changes in protein expression in two or more biological states.
How can you use quantitative proteomics?
LC-MS-based quantitative proteomics is a powerful analytical method that generates large and complex datasets that can be used to examine systematic changes in biological states, monitor specific pathways, or identify individual protein targets. The breadth of options can be difficult to navigate, and proper planning and sample preparation is key to success.
