Overview
Protein purification is a process in molecular biology that involves isolating one or a few proteins from a complex mixture, usually cells, tissues, or whole organisms. The purification process typically involves several steps, including cell lysis, clarification, and various separation techniques such as chromatography, electrophoresis, and centrifugation. These steps exploit differences in protein size, physico-chemical properties, binding affinity, and biological activity to separate the desired protein from other proteins and non-protein components. The process of protein purification has been refined over the years, with the introduction of new techniques and technologies, such as affinity chromatography and gel electrophoresis.
🎵 Origins & History
Protein purification has a rich history, dating back to the early 20th century when scientists first began to study proteins in detail. Today, protein purification is used in a wide range of applications.
⚙️ How It Works
The process of protein purification typically involves several steps, including cell lysis, clarification, and various separation techniques such as chromatography, electrophoresis, and centrifugation. These steps exploit differences in protein size, physico-chemical properties, binding affinity, and biological activity to separate the desired protein from other proteins and non-protein components. For example, size exclusion chromatography can be used to separate proteins based on their size, while ion exchange chromatography can be used to separate proteins based on their charge.
