Article Determining Criticality–Process Parameters and Quality Attributes Part III: Process Control Strategies—Criticality throughout the Lifecycle
The author applies the continuum of criticality to develop the process control strategy and move through Stages 2 and 3 of the new process validation lifecycle. With the most recent FDA …

Article Determining Criticality-Process Parameters and Quality Attributes Part I: Criticality as a Continuum
A practical roadmap in three parts that applies scientific knowledge, risk analysis, experimental data, and process monitoring throughout the three phases of the process validation lifecycle. A…

Article Ligand-Binding Assays and the Determination of Biosimilarity
During biosimilar development, it is necessary to demonstrate that the physicochemical properties, efficacy, and safety (e.g., immunogenicity) of the biosimilar are similar to those of the …

Article Implications of Cell Culture Conditions on Protein Glycosylation
The authors present a review of the techniques commonly used for glycosylation analysis. By Michiel E. Ultee, PhD, Dr. Richard Easton This article reviews the implications of cell-culture co…

Article Analysis of Glycosylation in Biosimilars
A step-wise process is used to characterize glycans and understand the functioning of a molecule for biosimilar development. The structures of protein drugs such as monoclonal antibodies are mad…

Article Elucidating Biosimilars Characterization
Traditional techniques such as X-ray crystallography and nuclear magnetic resonance (NMR) spectroscopy can be used for protein structure determination; however, the application to comparability studie…

Article Recent Advances in the Use of Exoglycosidases to Improve Structural Profiling of N-glycans from Biologic Drugs
However, their most common use is in glycan structure determination (7–11). Several enzymes with precise specificities have emerged over many years as the glycobiology field’s preferred analytical exo…

Article N-Glycan Analysis of Biotherapeutic Proteins
This article summarizes the approaches, challenges, and future perspectives for the characterization of N-glycans in biopharmaceutical products. By Aled Jones Protein glycosylation, the addi…

Article Defining Critical Quality Attributes for Monoclonal Antibody Therapeutic Products
An approach for establishing the CQAs of a mAb product by evaluating impact and uncertainty during risk assessment. A critical quality attribute (CQA) has been defined as “a physical, chemical, …
