Proteomics is a branch of biotechnology that deals with the techniques of molecular biology, biochemistry, and genetics to analyze the structure, function, and interactions of the proteins produced by the genes of a particular cell, tissue, or organism date, algorithms for image analysis of 2D gels have been developed. In case of mass spectroscopy, data analysis algorithms for peptide mass fingerprinting and peptide fragmentation fingerprinting have been developed. It is the large-scale study of proteins, particularly their structures and functions. Proteins are vital parts of living organisms, as they are the main components of the physiological metabolic pathways of cells.
