Which technique would be used to study proteins?

The technique used to study proteins is the Western Blot. This method specifically allows for the detection and analysis of proteins in a sample, providing insights into their presence, size, and quantity. During this process, proteins are first separated by gel electrophoresis based on their molecular weight. Following this separation, the proteins are transferred to a membrane where they can be probed with specific antibodies that bind to the target protein. The bound antibodies are then visualized, enabling the identification and quantification of the protein of interest.

This technique is essential in various fields, including biochemistry, molecular biology, and clinical diagnostics, because it provides both qualitative and quantitative data regarding protein expression and modifications.
