Duke University researchers have devised a method to dry and preserve proteins in a glassified form that seems to retain the molecules' properties as workhorses of biology. They are exploring whether their glassification technique could bring about protein-based drugs that are cheaper to make and easier to deliver than current techniques which render proteins into freeze dried powders to preserve them. Duke engineer and chemist David Needham describes this glassification process as "molecular...

New approach reduces number of routines needed to detect erythropoietins Austrian researchers have successfully developed a new electrophoretic method for detecting MIRCERA® and other erythropoietins (EPO) in the blood. The technique, using SARCOSYL-PAGE, has specifically enhanced sensitivity for MIRCERA, but does not alter the performance characteristics of SDS-PAGE for detecting other EPOs. Details of this study, funded by a grant from the World Anti-Doping Agency (WADA),...

Stacks of filter paper provide a realistic, easy-to-use medium for growing cells An insight from the labs of Harvard chemist George Whitesides and cell biologist Don Ingber is likely to make a fundamental shift in how biologists grow and study cells "“ and it's as cheap and simple as reaching for a paper towel. Ratmir Derda, a postdoctoral student co-mentored by Whitesides and Ingber at Harvard's new Wyss Institute for Biologically Inspired Engineering, has realized that by growing...

 Many proteins do not function by themselves as stand-alone units. Instead, multiple proteins associate to form larger structures called protein complexes. The May issue of Cold Spring Harbor Protocols (www.cshprotocols.org/TOCs/toc5_09.dtl) features a set of methods that can be used to analyze protein complexes. An additional featured article details the generation of viral vectors for gene transfer."Systematic Monitoring of Protein Complex Composition and Abundance by Blue-Native...
