Biologic products, including biosimilars, biogenerics and follow on biologic products, are often heterogenous and difficult to characterize slight changes in the protein structure of a protein products, such as glycosylation, disulfide bond linkage, deamidation/oxydation or the presence of some low level impurities, which can lead to a dramatic changes of its efficacy, immunogenicity and/or toxicity. Therefore, detailed characterization of a biological products is essential in the discovery and development of biologics.
