Next Generation Peptide Mapping with Ultra Performance Liquid ChromatographyUltra performance liquid chromatography (UPLC) is a new category of liquid chromatography that researchers are using to increase resolution, speed, and sensitivity in a variety of applications. These benefits result from packing columns with 1.7 ?m particles and using instruments that are optimized for such columns.

Designing a Shorter Vertical Leg for Sanitary Steam TrapsSteam traps are part of a steam-in-place system. The current design allots 18 in. of vertical leg for condensate backup. A design with a sensitive bellows has been proven in laboratory tests to need only 6 in. of vertical leg during the 15 min. of 121?C sterilization. Loads of 1 to 27 lb/h are covered by the capability of the new trap, equivalent to required steam for vessels 20 to 40,000 L.

A Statistical Method to Account for Plate-to-Plate Variability in Multiple-Plate Bioassaysby 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.

Final Word: The National Academies' Guidelines for Human Embryonic Stem-Cell ResearchOn April 26 the National Academies of Sciences and the Institute of Medicine released guidelines for human embryonic stem (hES) cell research, the result of eight months of deliberations by a human research ethics committee I co-chaired with MIT's Richard O. Hynes. Composed of scientists, physicians, lawyers, ethicists, a social scientist, and a private citizen, the committee held a two-day public workshop and numerous meetings. We also reviewed international guidelines, policies, and procedures in this field.

By the Numbers: What it Costs to Operate a Biopharmaceutical FacilityOperating costs are the white-hot issue in the boardrooms of our life sciences clients and they tend to rule the site selection process. A soft economy, worldwide trade competition, drug cost containment pressures from the US government, and a lean and mean message sent by the venture capital community mean that quantitative factors that focus on the cost of doing business are trumping qualitative lifestyle factors, especially when evaluating sites for a new biopharmaceutical facility.
