"Quantitative proteomics" refers to a scientific approach that analyzes and measures the proteins in a biological sample. It focuses on studying the amounts and changes in proteins present within different samples or conditions, which helps scientists understand how these proteins function and how they may contribute to various diseases or biological processes.
