Immunopurification is a term often used in biochemistry to describe the process of isolating a specific protein or molecule from a complex mixture. Synonyms for immunopurification include immunomagnetic separation, affinity chromatography, and antibody-based capture. Additionally, similar techniques such as immunoblotting, immunoprecipitation, and biotin-streptavidin purification can also be used to achieve similar results. These methods rely on the use of specific antibodies or other molecules that bind to the target protein or molecule, allowing for its isolation and purification. Overall, selecting the appropriate method for immunopurification depends on factors such as the sample type, the target molecule, and the desired purity and yield.
