Zetasizer used for protein conformation
studies
At the East Asian Biophysical Society meeting in Okinawa (12-16 November 2006) Kouhei Shiba, from Sysmex will discuss benefits of using the Zetasizer Nano to study conformational changes in proteins
The Zetasizer Nano uses the technique of dynamic light scattering (DLS) to rapidly and accurately measure particle size Its high sensitivity and precision temperature control are critical factors that allow thermally dependent structural changes to be detected at very low volumes/concentrations

Nanoparticle characterisation using the Zetasizer Nano from Malvern Instruments is providing essential information for researchers working on drug delivery systems at UK's newest school of pharmacy
Protein structure correlates closely with function and is a parameter of significant interest.
Using DLS, conformational changes are detected by measuring small differences in the hydrodynamic diameter of the molecule.
The technique is shown to have some advantages over differential scanning calorimetry for the study of structural change, and can also be used to measure the affinity of carbohydrate binding proteins, such as Lectin, with monosaccharides.
The Zetasizer Nano is a powerful easy-to-use protein characterization tool.
Offering exceptional sensitivity and accuracy it allows protein molecules with a hydrodynamic radius down to 0.3nm to be measured at concentrations of 0.1mg/ml or less.
Incorporating a facility for absolute molecular weight measurement, user-friendly software and automated analysis protocols it is the ideal choice for protein laboratories. Request a free brochure from Malvern Instruments ...
