While unpurified antibodies are suitable for a number of applications, purified antibodies are required for assays based on known concentration of antibody, for chemical modifications such as radiolabeling or conjugation with fluorochromes, or for structural modifications such as production of F(ab')2 or monvalent Fab fragments. This unit contains protocols for purification of IgG by ammonium sulfate precipitation coupled with size-exclusion chromatography, Protein A- and Protein G-affinity chromatography, immunoaffinity chromatography, and ion-exchange chromatography.

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 Chromatography01:29

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.
