Proteomic analysis is the large-scale study of proteins, which are essential molecules that perform various functions in living organisms. This analysis helps scientists understand the structure, function, and interactions of proteins within a cell or tissue. By examining the complete set of proteins, known as the proteome, researchers can gain insights into biological processes and disease mechanisms. Techniques used in proteomic analysis include mass spectrometry and two-dimensional gel electrophoresis. These methods allow for the identification and quantification of proteins, enabling comparisons between different samples. This information is crucial for fields like biomedical research and drug development, where understanding protein behavior can lead to new therapies and treatments.
