Expert Support for Development and Characterization

Supporting robust data requirements at every phase of the project cycle

The clinical and commercial success of biotherapeutics hinges on the development of robust, reproducible, analytical methods. High-resolution mass spectrometry is a powerful tool used at KBI Biopharma for analytical strategies concerning complex samples. In support of biotherapeutics across the board, KBI's Mass Spectrometry Core Facility has championed the characterization and management of proteins, active pharmaceutical ingredients (APIs), and impurities through identification, characterization, assessment, and quantitation. At KBI, we are true partners working hand-in-hand with clients to conquer complexities and develop lasting solutions to the analytical challenges that come with the development of biologics.
