HPLC Proteomics
HPLC Proteomics is a technology that integrates high-performance liquid chromatography (HPLC) with proteomic analysis. HPLC efficiently separates complex protein mixtures, while proteomics focuses on studying the complete protein expression profile of cells, tissues, or organisms at specific time points. By combining these techniques, HPLC proteomics provides a comprehensive approach to analyzing proteins in biological samples. Specifically, HPLC separates proteins or peptides with high resolution, which are then identified and quantified using mass spectrometry or other techniques. This method not only identifies proteins but also uncovers post-translational modifications, interaction networks, and the dynamic changes of proteins in biological processes. In biomedical research, HPLC proteomics has broad applications. By analyzing changes in protein expression under disease conditions, potential biomarkers can be identified, providing valuable insights for early diagnosis, treatment, and prognosis of diseases. In drug development, HPLC proteomics is used to screen potential drug targets and assess the mechanisms of drug action. In environmental sciences, it is extensively employed to monitor the effects of pollutants on organisms and reveal complex interactions within ecosystems.
