Abstract

High-performance membrane chromatography (HPMC) and HPLC hydroxyapatite chromatography were compared for their efficiency in purifying immunotoxins (ITs) containing the ribosome-inactivating protein clavin, which is characterized by a high anionic charge and a low molecular mass. Both methods efficiently removed unreacted clavin from the conjugate crude mixture, but only the cation-exchange HPMC allowed efficient single-step separation of the unreacted monoclonal antibody (mAb) from ITs obtained by different coupling procedures.
