The availability in Instruct of the most advanced instruments for Multi Angle Dynamic Light Scattering (MALS) combined quasi-elastic light scattering (QELS) detectors allows the user to carry out a detailed biophysical characterization of biomolecules in solution. The measure of the intensity of laser light, scattered at different angles by macromolecules passing through the flow cell and the analysis of the autocorrelation function of the laser light fluctuations allow the calculation of: the concentration of the biomolecules in solution, the molecular weight, the radius of gyration (rg), the translational diffusion coefficient (Dt) and the related hydrodynamic radius (rh). The technique is extremely sensitive and provides information on the shape and aggregation state of the biomolecules in solution.
