Core Tip

Core Tip: Proteomics is the complete evaluation of the structure and function of proteins to understand an organism’s nature. Mass spectrometry is an essential tool that is used to profile proteins in the cell. However, biomarker discovery remains the major challenge of proteomics because of the complexity and dynamicity. This review highlights the types of proteomics, the available proteomic techniques, and their applications in different research fields.
