A new, freely downloadable brochure available on the Malvern Instruments website provides extensive information on the many applications of the companys Zetasizer Nano system for the study of proteins. Detailed information about protein applications is also available on the protein section of the website.Optimized for the characterization of proteins in solution, the Zetasizer Nano features advanced light scattering technology and offers the highest sensitivity and accuracy of any system available. The brochure illustrates its use for protein size and molecular weight measurement, screening for protein crystallization conditions, determining aggregates, and measuring melting points. Also described is the way the system can be used to monitor changes over time, pH and sample concentration.The brochure is available at www.malvern.co.uk/common/downloads/MRK653-01.pdf.
