A Study Following U.S. EPA Method 8081 Guidelines

Work performed in conjunction with the Institut Pasteur, Paris, France Cations are specifically recognized by numerous proteins. Despite their small size, their specific interactions with highly charged residues allow them to induce significant conformational changes on their binding proteins.

Whey is a by-product of the cheese-making process, and Whey Protein Isolate (WPI) is a dietary supplement and food ingredient created by separating components from milk. It contains a high percentage of pure protein and can be pure enough to be virtually lactose free, carbohydrate free, fat free, and cholesterol free. In this application note, a sample of WPI was characterized using the Viscotek TDAmax. The 4 main components in this mixture were separated and individually characterized.

The study of exosomes and other cell-derived microvesicles is an area of rapidly rowing importance and the subject of intense interest and research. The previous lack of suitable methods for their detection, analysis, enumeration and phenotyping is proving to be a significant limitation in these studies. This document shows the degree to which the technique of Nanoparticle Tracking Analysis (NTA) is helping to address these problems.

Whilst at Riva 2014 (the 38th ISCC and 11th GCxGC Symposium), Rich Whitworth, editor of The Analytical Scientist, invited three key participants of the conference to take part in an exciting new video projec

New components and measurement techniques continue to be introduced for the Zetasizer Nano. New to the system are a Surface Zeta Potential accessory and a new diffusion barrier method for improved zeta potential measurements of protein samples. Why is the Malvern Zetasizer Nano so popular and found in a broad range of applied and fundamental scientifi c projects across all industries and fields? Because, it is simply the most dynamic and broad ranged instrument on the market for solving technical issues in today’s research environment and it continues to evolve with new capabilities. Here are 10 reasons why you should choose the Zetasizer Nano:

Taking gas chromatography into the field has the potential to detect crop disease sooner

For our second episode, we stay in Italy and speak with Chiara Cordero from the University of Turin

The Zetasizer µV (MicroV) is a dual purpose light scattering instrument designed specifically for the analysis of proteins. Firstly, it is a highly sensitive cuvette based dynamic light scattering instrument with the same great performance as the market leading Zetasizer Nano. Secondly, by simply changing the cell, it becomes an absolute molecular weight and size detector that can be added to any Size Exclusion Chromatography system (such as the Viscotek TDAmax).

The Zetasizer Nano is the world's most widely used light scattering system, for measuring size, zeta potential and molecular weight. Applications range from characterizing high concentration colloids and nanoparticles, through to measurement of proteins and macromolecules in their native state, requiring as little as 12 microlitres of sample. The Zetasizer Nano can be used for the comprehensive characterization of proteins, colloids and nanoparticles, and is simple to use, highly sensitive, versatile and fast! This videos shows how quickly and easily a measurement can be made on the Zetasizer Nano.
