PolyQuant offers sensitive and quantitative detection of host contaminant proteins by mass spectrometry. Our method is independent of antibodies and thus can be applied to any production organism. The method is equally suited to analyze purified proteins or more complex therapeutics, e.g. bacterial phages. Our sample preparation technique has been successfully applied even to difficult matrices, like complex buffers or gels.

Our services start from quick screenings to support the optimization of the purification processes, up to GMP-certified release testing of therapeutic proteins and phages.
