What Is Antibody Purification?

The preparation of highly specific, high titer antibodies is the basis of experimental immunology technology. The quality of antibodies will directly affect the success or failure of the experiment. Antibodies prepared by different methods are often mixed with multiple heterologous proteins. In order to obtain antibodies with relatively single components or use the antibodies for specific purposes, antibody purification is required. From the perspective of composition, antibody molecules are a class of protein molecules. Like other proteins, they have a certain isoelectric point, solubility, chargeability, and hydrophobicity. They can be separated by electrophoresis, salting out precipitation or other chromatography techniques , Purification.
