Western Blot Tests, also known as Immunoblotting, is a process that helps to detect specific proteins from a complex mixture of proteins in biological samples. Western blot tests are commonly used in biomedical research and clinical diagnostics. However, there are several synonyms for Western blot tests, which include protein blotting, protein immunoblotting, and protein transfer. These synonyms describe the same fundamental process of detecting proteins by the transfer of their separated components onto a membrane where they can be identified with specific antibodies. Whatever the use case may be, Western blot tests and their synonyms are vital techniques that are widely used in molecular biology.
