How to Purify Antibody from Serum When antiserum has been collected for purification, ammonium sulfate precipitation is performed. This removes many sticky proteins from the antiserum and allows for a cleaner preparation of material to be subjected to the affinity column.

To isolate the antibody with a minimum of contamination from other serum proteins, a three-step procedure is often used. The antibody source (serum, supernatant, Ammonium sulfate precipitation is a method used to purify antibodies by altering their solubility from ascites,serum or hybridoma supernatant. It is a specific case of a more general technique known as salting out. To precipitate a dissolved protein, it is necessary to reduce the number of hydrogen bonds between solvent and the proteins. The antibodies from 100 µL human serum were purified with a monolithic protein A column with a flow rate of 5 mL/min and a total run time of 1.5 minutes. The chromatogram is shown in Fig. 1. Peak A depicts the flow-through of unbound proteins.
