immunoprecipitation assay

IEDB

An analyte assay in which an input material is mixed with antibodies and bound antigen:antibody complexes are separated out using immunoprecipitation. Either the antibody has known specificy, and the antigen mixture is tested for the presence of a specific antigen, or the antigen solution is well defined and the antibody solution is tested for the presence of antigen specific antibodies.

Determining if a cell is producing a protein using a protein specific antibody to immunoprecipitate the cell lysate. Determining if the serum of a patient contains antibodies against HBV core protein by immunoprecipitating purified HBV core protein with the patients serum.
