Protein analytics and quality control

Protein analytics and quality control

We offer solutions for various types of proteomics projects:

More information

Production of biosimilars and biologically derived pharmaceuticals (e.g. recombinant protein production) requires sophisticated quality control. Our technology allows monitoring of quality parameters of the major protein component like validation of the major protein component, determination of sequence integrity and post-translational or chemical modifications. Additionally, we offer detection and quantification of sample impurities (host cell protein analysis).

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.
