Proteomics is the large-scale study of proteins, particularly their functions and structures. It plays a crucial role in understanding biological processes and disease mechanisms, as proteins are essential for various cellular functions. By analyzing the proteome, researchers can identify biomarkers for diseases and develop targeted therapies. The field of proteomics utilizes advanced techniques such as Mass Spectrometry and Two-Dimensional Gel Electrophoresis to separate and identify proteins in complex biological samples. This information can lead to significant advancements in personalized medicine and drug development, ultimately improving patient outcomes and healthcare strategies.
