State-of-the-Art vs. Tried and Trusted
By Anita Bate, PhD
Factors such as quality, time to market, and regulatory changes are forcing an evolution to state-of-the-art analytical test methods.
Rapid Microbiological Methods and the PAT Initiative
By Jeanne Moldenhauer
The methods used in most microbiological test laboratories originated in the laboratories of Koch, Lister, and Pasteur. While numerous changes have occurred in the chemistry laboratory, there have been limited improvements in methods used for microbiological testing.
Submitting Advanced Bioanalytical Test Methods for Regulatory Approval
By Stephan Krause, PhD
FDA and regulatory agencies worldwide have recently approved many advanced bioanalytical technologies. Receiving approval of advanced test methods for new biopharmaceutical products is relatively straightforward, provided clinical and process validation data are generated by the same (or at least similar) test method. However, regulatory approval becomes more difficult and time consuming when compendial test methods or test methods for already licensed biopharmaceuticals are changed.
Method Validation Guidelines
By Alex D. Kanarek, PhD
"The objective of validation of an analytical procedure is to demonstrate that it is suitable for its intended purpose" (International Conference on Harmonisation Guideline Q2A).1 "Methods validation is the process of demonstrating that analytical procedures are suitable for their intended use" (US Food and Drug Administration Draft Guidance for Industry, 2000 ).2
Biopharmaceutical Characterization Techniques for Early Phase Development of Proteins
By Shelia G. Magil, Ph.D.
Characterization of biopharmaceuticals (proteins) during early development is done for several reasons. The most important reason is the need to have supporting data that demonstrates the comparability of material used throughout development. This is particularly important as the production process is optimized and small changes in the process may affect the structure of the product. Demonstration of comparability of proteins produced throughout product development is more complicated, due to the inherently heterogeneous nature of many biologicals.
Bioanalytical Development Tools
By Peter M. Silverberg
Nearly every process conducted in a biotechnology company requires analytical methods to back it up. Since BioPharm's last guide published in December 2001,1 scientists have developed exciting, new tools for conducting research. Listed here is a sampling of new technological developments unveiled in 2005.
