Use of DLS/Raman to Study the Thermal Unfolding Process of Lysozyme
28 Jul 2014This white paper demonstrates the viability of using a combined DLS/Raman instrument for study of the lysozyme unfolding process as a result of thermal stress. Thermal jump and ramp experiments are performed on lysozyme solutions at pH 4. Raman and DLS results indicate that any protein structural and size changes that occur as the result of increased temperature (up to 80°C) are reversible.

Raman SpectroscopyRaman spectroscopy is used to discern the vibrational and rotational states of molecules and hence the chemical composition of a sample by measuring the inelastic scattering of monochromatic light. Explore a range of Raman spectrometers, including handheld/portable Raman spectrometers for QC/QA labs and in situ spectrometers for processes. Conduct Raman imaging for microanalysis of mixed samples using a Raman microscope. Raman spectrographs are also available.

Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
