title: [Enzymatic splitting of antibodies bound to immobilized antigen as a means of Fab fragments preparation].
abstract: A method of Fab fragments preparation by enzymatic splitting of antibodies bound to specific antigen immobilized on an insoluble support is described. The complex of rat muscle glyceraldehyde-3-phosphate dehydrogenase (GAPD), immobilized on Sepharose 4B, with anti-rat GAPD rabbit antibodies was digested with papain. The antigen was inaccessible to proteolysis under conditions employed. After 4 hrs of incubation with papain the antibody was completely split into non-precipitating fragments. The products of proteolysis not bound to Sepharose, were eluted with 0.1 M givcine buffer pH 2.5, and shown to correspond to Fab fragments.
