Definition
Western blotting is a laboratory technique used to detect specific proteins in a sample by separating them through gel electrophoresis, transferring them onto a membrane, and probing with antibodies that bind to the target protein. This method allows for the identification and quantification of proteins based on their size and abundance.
Summary
Western blotting is a powerful technique used in molecular biology to detect specific proteins in a sample. It involves several steps, including gel electrophoresis to separate proteins, transferring them to a membrane, and using antibodies to identify the target proteins. This method is widely used in research and clinical settings to study protein expression and function. The process of Western blotting allows scientists to visualize and quantify proteins, making it an essential tool in various applications, such as disease diagnosis and drug development. Understanding the principles behind Western blotting, including the roles of antibodies and gel electrophoresis, is crucial for anyone working in biochemistry or related fields.
