Dynamic light scattering system adds protein measurement and microrheology capabilities to Zetasizer family.
According to Malvern, the technology stands apart due to its performance specifications for both size and zeta potential measurement.
One of the most significant applications is the measurement of the zeta potential, or electrophoretic mobility, of proteins.
This process is simplified by the inclusion of a new protein mobility measurement type in the software that controls data acquisition, guiding the user through the measurement and assesses and reports on data quality.
The protein mobility measurement package is included with the Zetasizer Nano ZSP instrument as standard.
As well as the suite of new protein-specific features, the new version of Zetasizer software, launched together with the Zetasizer Nano ZSP, enables a brand new type of measurement on the instrument – Microrheology.
This DLS-based optical technique allows rheological characterisation of weakly-structured and highly strain-sensitive materials using only microliter sample volumes.
Among its applications are measuring the viscosity of polymer and protein solutions and determining the onset of protein aggregation.
Malvern’s extended Zetasizer family now includes the full Zetasizer Nano range of systems for characterising size, molecular weight and zeta potential measurement; the Zetasizer APS for automated protein size measurements in multiwell plates; and the Zetasizer µV designed for protein size and molecular weight measurements in both cuvette and chromatography modes.
