by Patrick Clinton, BioPharm International As FDA moves toward a new vision of GMP regulations, BioPharm International asked industry experts some key quextions: What form will risk-based GMPs take? What are the benefits and costs for biotech? Will the change really encourage innovation? And, most important, can FDA leaders get field inspectors to buy into the new approach?

McEntire Amino acid analysis (AAA) of well-recovered residues offers an easy way to calculate the absorptivity constant for a known protein. The method provides an absolute measure of protein concentration, free from interference from water, excipients, and bound salts. This article demonstrates a qualified method for determining protein content by AAA.

by David Venables, Q-One Biotech Ltd. Approximately 75 vendors offer biological contract manufacturing services in Europe ? a manageable data set for analyzing the services they provide.
by Vicki Cloutier, Guidant Corporation It's not enough to train your staff ? you have to keep training them. A good learning management system can help.
High-purity low-endotoxin sugars improve robustness and stability of protein formulation and improve drug product quality.
Understanding differences in bioreactor lifecycle, design space, and product platforms is important for selecting a bioreactor type.

by Stephen F. Gorfien, GIBCO Cell Culture R&D, Invitrogen Corporation William Paul, David Judd, Lia Tescione, and David W. Jayme Cell density, longevity, and expression are the economics of cell cultures in biopharmaceutical production ? and rich growth media are the investment. Glucose and glutamine are primary energy sources for culture growth, but their associated metabolic wastes can actually harm cell cultures. Adapting cell lines to reduced levels of glucose and glutamine, then feeding the culture chemically defined nutrient supplements, increases cell viability, maximizes cell density, and increases product expression.
by John Dougherty, Eli Lilly and Company, Rohin Mhatre, Biogen, Inc., and Stephen Moore, CDER FDA and biopharmaceutical industry stakeholders reach consensus on critical issues related to the use of peptide maps as identity tests for proteins and on their usefulness for lot release tests. The results of that discussion are presented here.

by Lon Crosby Farmers may be the pharmaceutical producers of the 21st Century. The technology exists, and practices commonly used in agriculture can be modified to meet envisioned GMPs ? and those modifications are within reach.

by Craig R. Kaufman, Orrick, Herrington & Sutcliffe LLP, Rebecca Burton, and Anne-Marie Dinius Your patent portfolio does not make money sitting in a file cabinet. Extracting its value requires both market surveillance and an effective litigation or licensing strategy.
by James D. Williams, Virginia Polytechnic Institute and State University, Jeffrey B. Birch, and Steven Walfish Statistics don't lie, but if you don't include appropriate data, the resulting statistical analyses can be misleading. In biopharmaceutical development, if the variability from several different microplates is not addressed, assays testing the relative potency against a standard can be inaccurate. A statistical method that accounts for plate-to-plate heterogeneity is needed ? and presented here.

by Robert J. Seely, Amgen, Inc. Louis Munyakazi, John Haury, Heather Simmerman, W. Heath Rushing, and Thomas F. Curry Determining whether a data point is an "outlier" ? a result that doesn't fit, that is too high or too low, that is extreme or discordant ? is difficult when using small data sets (such as the data from three, four, or five conformance runs). The authors show that the Weisberg t-test is a powerful tool for detecting deviations in small data sets.
