West Western blotting, also known as Western blotting or protein blotting, is a widely-used laboratory technique in molecular biology and biochemistry. It is primarily used to detect specific proteins in a sample and is a crucial tool for studying protein expression and identification. Although there are no direct synonyms for the term "West Western blotting", it can be referred to as immunoblotting or protein immunoblotting. These terms describe the same technique of transferring proteins onto a membrane and then detecting specific target proteins using specific antibodies. Regardless of what it is called, West Western blotting remains a fundamental analytical technique in biological research.
