摘要:
Some aspects of the disclosure include methods for comparing the higher order structures (HOS) of proteins using covalent labeling agents which allow for the direct comparison of changes in the HOS of protein therapeutics using mass spectrometry. The inventive methods can be used to access the effect of changing the process of producing and/or storing complex biologic compounds as well as determining if the HOS of a protein therapeutic has spontaneously changed during storage. Still other uses include comparing branded biologic therapeutic compounds to biosimilar compounds, and measuring changes in the aggregation states of proteins.
