Antibody purification is a specialized technique that involves the isolation and purification of antibodies from a mixture or solution. This is a crucial step in many research and diagnostic applications as isolated and pure antibodies can be used to accurately identify and target specific antigens. The process of antibody purification requires a combination of techniques such as chromatography, filtration, and precipitation to separate the desired antibodies from other unwanted molecules. Proper antibody purification is essential for producing high-quality antibodies that can yield accurate and reproducible results.
