Abstract     Different chromatographic methods including chromatofocusing are used for separation of manganese peroxidase (MnP) isoforms and their isolation from the fungal growth medium. We tested strong anion exchange methacrylate based monolithic columns as a stationary phase for fast separation of MnP's. Sodium acetate buffers of two different pH values (6 and 4) were used for formation of reproducible pH gradient. The entire cycle, involving analysis and column regeneration, was completed in 3 min. Use of pH gradient showed better MnP isoform separation comparing to the salt gradient, while application of combined pH-salt gradient, resulted in further improvement
