Production of biosimilars and biologically derived pharmaceuticals (e.g. recombinant protein production) requires sophisticated quality control. Mass spectrometry assisted proteomics offers a fast and efficient alternative to methods like western blotting or ELISA. Foremost, it allows you to identify hundreds of proteins with a single experiment. Its high sensitivity enables the accurate and reproducible detection and of even low abundant proteins. Our technology covers different quality control approaches: Discovery proteomics (unbiased detection of proteins, host cell protein analysis, expression profiling, etc.) Targeted proteomics (protein quantification, discrimination between isoforms, expression analyses, determination of degradation products, stoichiometry of protein complexes, post-translational or chemical modifications etc.) Peptide mapping (determination of sequence integrity)
