Applied Analytical Techniques to Monitor IsoAsp in Biologics Formulation Develop - ERP Spain.com - España y América Latina

The development of a suitable biologic formulation occurs often before analytical methods are validated. Certain chemical modifications are critical to monitor during the development process as they may cause protein instability and reduce biologic efficacy. Aspartic acid isomerization is one such modification, but is arguably the most difficult to detect. Analytical tools to track IsoAsp are discussed that can aid in making formulation decisions before the availability of qualified methods.
