Measurement system

!%Wyatt Technology Corp.%! has released a brochure on its Wyatt Calypso system for the automated characterization of molar masses and macromolecular interactions. Available in pdf, the four-page document describes the batch light-scattering measurement system and its applications, which include process improvement, protein crystallization, self-assembly/aggregation, drug discovery and reversible macromolecular associations. It describes how the instrument creates and delivers sample concentration gradients, how it acquires and analyzes multiangle light-scattering and concentration data, and how the built-in automation leads to repeatable measurements of Zimm plots, kinetics, and reversible self- and heteroassociations.
