Characterize proteins with this analyzer

The new Zetasizer Nano ZSP is a high-specification dynamic light-scattering system that delivers unique protein-characterization capabilities in a single, easy-to-use instrument. The instrument enables highly sensitive measurement of zeta potential, for rapid measurement of the electrophoretic mobility of proteins, and subsequent calculation of the key parameter of protein charge. Measuring protein mobility by dynamic light scattering is faster and more convenient than conventional methods, such as capillary electrophoresis and iso-electric focusing, says the company. This instrument only requires 20 µL of sample, and measures concentrations down to 1 mg/mL. — Malvern Instruments Ltd., Malvern, Worcestershire, U.K.
