The Analysis and Characterization of
Protein Therapeutic Drugs
(Including
Protein Structure and Function)
Instrumental Tools and
Techniques for the Characterization and Analysis of
Biotechnology-derived Polypeptide Therapeutics
In late 1995, the FDA initiated important changes in the
regulation of protein therapeutic drugs which led to harmonization in the regulation
of protein drugs and small molecule drugs. This change placed considerable
emphasis on the analytical technologies used to characterize and analyze
protein therapeutics. At the first
“WCBP” Conference in January of 1997 a need was identified for a professional
development short course focused on training scientists in just these
analytical technologies. The resulting course was first presented in March of
1998 and has since been presented to over 2000 scientists worldwide. While
undergoing many changes and revisions over the years, the course, now titled
the Analysis and
Characterization of Protein Therapeutic Drugs, has remained true to the original
mission of training scientists in the current, state-of-the-art, technologies
used to meet the challenges inherent in analyzing and characterization of
complex biomolecules.
The Analysis and Characterization of Protein Therapeutic Drugs immerses those attending
in the practical aspects of characterizing and analyzing therapeutic proteins
and presents in an adsorbing manner the fundamental principles and practical
uses of three fundamental analytical technologies. Topics extraneous to protein
analysis are eliminated, allowing the course to focus on the points of each
technology essential in protein characterization. Those attending leave with
a clear sense of where each technology is used and how to most effectively
implement each technology in developing and using effective, efficient
analytical methods for characterizing and analyzing therapeutic proteins.
The Analysis and Characterization of Protein Therapeutics Drugs
begins by providing a detailed description of protein structure and function
followed by a complete discussion of protein modifications and degradations. It
then teaches the essential principles and practices of three important
instrumental analytical technologies as they relate to the analysis and
characterization of polypeptides:
n Chromatography,
especially reversed-phase HPLC
n
Capillary Electrophoresis
n
Mass Spectrometry
Day 1
Morning: Protein Structure and Function. The class begins by outlining the various structural forms of
proteins, describing the nature and functions of the natural amino acids, secondary, tertiary and quaternary structure. The role and
purpose of tertiary structure in protein bioactivity is explained. Internet
resources are mentioned.
Afternoon: Protein modifications and degradations discuss natural post-translational
modifications, degradations and engineered modifications to therapeutic
proteins. The class will include a description of
protein degradations such as deamidation, oxidation,
denaturation and aggregation, post-translational modifications such as
glycosylation and disulfide bonds and engineered modifications such as pegylation and drug conjugates. Peptide mapping is
described as a foundation to discuss the analytical technologies. Emphasis is
placed on determining and defining Critical Quality Attributes and how to
monitor these.

an expert in High Performance Liquid Chromatography. He is very familiar with
capillary electrophoresis and mass spectrometry as applied to the analysis of
polypeptides. Dave has provided instruction on HPLC and the use of HPLC in the
analysis and characterization of polypeptides for many years. He has a facility
for explaining the concepts and practices involved in the analysis of
polypeptides in a manner that makes them clear and easy to understand. Course
