IgG can be purified, as described here, by ammonium sulfate precipitation followed by size-exclusion (SE) chromatography. This is the least expensive option available for purification of antibodies. Protein A- and protein G-affinity chromatography are the fastest methods for purifying antibodies, but they are not effective for all subclasses of rat antibody. A protocol for affinity chromatography using anti-rat antibody is provided for purification of rat antibodies. Ion-exchange (IEX) chromatography is described for purifying intact monoclonal and polyclonal antibodies and antibody fragments.

Immunoprecipitation01:20

Immunoprecipitation

Immunoprecipitation, or IP, is a widely used technique that employs protein-antibody interactions to isolate proteins or protein complexes in their native state for studying protein-protein interactions, quaternary structures, or supramolecular complexes. Various modifications of the technique, including chromatin IP, cross-linking IP, and fluorescence IP, are commonly used.

Types Of Column Chromatography

The stability and compatibility of column material with samples are crucial for efficient purification in chromatographic techniques. Various operating parameters such as pH, temperature, or solvent affect the packing of the column material, thereby determining the purification efficiency. The choice of column material also plays an essential role in deciding the operating parameters and can be modified based on the proteins that need to be purified.
