With the popularization of the mass spectrometer and the improvement of technology, proteomics has moved from the traditional two-dimensional electrophoresis to the era of big data based on mass spectrometry. Bioinformatics is a rising cross-discipline, which comprehensively uses the tools and methods of biology, medicine, pharmacy, statistics, computer science, and other disciplines to mine and explain the biological significance of biological data. MitochondriaSci's bioinformatics analysts specialize in mitochondrial proteomics data knowledge mining and quickly discover a large number of protein-protein interaction data.
