Analytical Methods

For modern biopharmaceutical research, it is necessary to combine different analytical methods with each other in order to obtain a more complete assessment of the protein structure and function.

Characterization of Biopharmaceuticals and Biosimilars
Working with biologic drugs represents a huge analytical effort to deeply understand the whole molecule characteristics. Different methods and technologies are needed to get the analytical fingerprint. An extensive analytical characterization based on an ortogonal approach is a key element for the project success.

Benefit from reliable analytical capabilities
Reliable, robust analytical methods are imperative for successful drug development and commercialization. Method development, qualification, and validation play a pivotal role in understanding the critical quality attributes of the molecule, which help to define the robust control strategy required to manufacture and commercialize biologic molecules.
