Production of biosimilars and biologically derived pharmaceuticals (e.g. recombinant protein production) requires sophisticated quality control. Besides identification of the major protein component after purification, it is also necessary to determine co-purified components like host cell proteins and the integrity of the purified protein.
PolyQuant provides solutions for the identification and quantification of the proteinaceous compounds in a mixture, the detection of sample impurities, chemical modifications etc.
We offer both primary scanning for possible contaminants via untargeted proteomics and full method setup for routine scanning of known common contaminants via targeted proteomics.
