This unit describes electrophoretic separation and identification of large proteins from a complex protein mixture. Agarose gel is utilized for the electrophoretic matrix, and detection of proteins is accomplished by transfer of the proteins to a membrane that is probed with specific antibodies and chemiluminescence reagents. Alternatively the protein can be detected in the gel using radiolabeled antibodies and autoradiography.
