title: Membrane filtration affinity purification (MFAP) of dehydrogenases using cibacron blue.
abstract: The method for purification of biomolecules by a combination of affinity interactions and membrane filtration for separation of unwanted material has been found to be of interest for large-scale work. This study examines the suitability of silica nanoparticles as carriers in the process. Alcohol dehydrogenase and lactate dehydrogenases were chosen as target molecules to be purified. The binding capacity was found to be comparative to what is obtained for high-performance liquid chromatography (HPLC) packing material. Both binding and desorption of the enzymes were found to be effective. The limiting factor of the process was the filtration flow rate.
