Electrophoretic stretching of DNA reaches new lengths
Electrophoresis, both in gels and in polymer solutions, has been widely used for decades to isolate and purify DNA and protein, yet a complete description of the mechanisms by which polyelectrolytes are separated using this technique has not been developed.  The goal of graduate student Sean Ferree is attempting to describe the dynamic stretching properties of DNA.

Protein causes insanity
Protein aggregation has been implicated in nearly 20 diseases and is a serious problem during the preparation of protein pharmaceuticals. We are currently trying to improve our understanding of the biophysical phenomena underlying protein aggregation by exploiting both experimental and computational approaches. by Troy Cellmer Full Text »

Who's fat?
The purification of omega-3 fatty acids can be achieved through selective crystallization of saturates and lower unsaturates in inclusion compounds.  An effective clathrate system for this application has been developed through the crystal engineering of guanidinium organodisulfonate hydrogen-bonded networks.  by Jason Voogt.

Enzyme Biotechnology
RADKE LAB, UC Berkeley - Enzymes find increasing use in aqueous-organic systems for commercial production of specialty and intermediate-scale chemicals. The kinetics of enzyme reactions in supercritical fluids, reverse micelles and microcapsules has been the subject of earlier research in our laboratory. Current research is focused on the role and kinetics of enzymes at interfaces. The adsorption of proteins at oil/water interfaces is a complex phenomenon affecting enzymatic catalysis, biomaterials compatibility, and protein stability in formulations.
