| Abstract: | The chromatographic separation of crude papain preparations on Sephadex G-50 (fine) enables pure papain to be obtained in a single step. Immunochemical techniques have been found to be very convenient for testing the purity of the individual chromatographic fractions. A general approach is presented that makes it possible to follow the course of the chromatographic purification of any immunogenic compound by simple qualitative immunochemical techniques that can be applied in any laboratory. |
