Technological innovations have increased our potential to evaluate global changes in protein and small molecule levels in a rapid and comprehensive manner. This is especially true in mass spectrometry-based research where improvements, including ease-of-use, in high performance liquid chromatography (HPLC), column chemistries, instruments, software, and molecular databases have advanced the fields of proteomics and metabolomics considerably. Applications of these technologies in clinical research include biomarker discovery, drug targeting, and elucidating molecular networks, and a systems-based approach, utilizing multiple "omics," can also be taken. While the exact choice of workflow can dramatically impact the results of a study, the basic steps are similar, both within and between metabolomics and proteomics experiments. Although gel-based methods of quantitation are still widely used, our laboratory focuses on mass spectrometry-based methods, specifically protein and small molecule profiling.
