Protect Your Proteins

Eliminate vulnerabilities in your western workflow

Western blotting, also known as immunoblotting, is a well established and widely used technique for the detection and analysis of proteins. This detection method is based on building an antibody/protein complex via specific binding of antibodies to proteins immobilized on a membrane and detecting the bound antibody with one of several detection methods. Western blotting Analysis is one of the most commonly used methods in life science research.

Sigma-Aldrich is committed to providing the research community access to high quality Western reagents throughout the entire workflow to ensure reproducible and accuracy of results.
