Protein Characterization Services
Analytical Protein Characterization ensures the identity, purity, structural and conformational integrity and activity of a protein. We perform a number of routine protein analyses throughout all project stages. If needed, we can submit your samples for additional methods of characterization. We also offer specialized protein characterization services for purified proteins.
