![]() In fully automating light scattering measurements using microwell plates, the Zetasizer APS makes screening and repeating sample measurements easy, and allows different types of measurement to be made on a single plate. It also allows further characterization of the protein size distribution to determine the presence and proportion of aggregates, giving increased control over the condition of a protein during both purification and method development. There is no compromise in data quality due to automating the measurement, the company claims.ĭynamic light scattering measures the thermal diffusion of proteins and nanoparticles in solution, enabling size determination. ![]() ![]() The Zetasizer APS allows investigation of a protein’s condition at different stages of the purification process, and at later stages of formulation under a range of environmental conditions.Īccording to Malvern, the measurement technology used delivers results with exactly the same high reproducibility users would expect from a research grade batch DLS system. ![]() Malvern Instruments has launched the Zetasizer APS, a new dynamic light scattering (DLS) system which automates size measurements of samples in 96- or 384-well microplates.ĭesigned primarily for protein specialists, the new system is fully automated, simply requiring users to insert the plate and press start. ![]()
