A useful webpage on Science Direct pulls together overviews of interesting published scientific papers on protein aggregation. Protein aggregation can occur through chemical or physical degradation and is dependent on the thermodynamic stability of the protein's native state. The driving force behind protein aggregation is the reduction in free surface energy by the removal of hydrophobic residues from contact with the solvent.

European regulation about operation of x-ray instruments is changing to reflect increasing concern over your safety. To ensure the safe operation of your x-ray instruments they must now be checked on a regular base. A simple hardware patch is now available for all users of our BI-XDC X-Ray Disc Centrifuge to ensure your system is fully compliant with the latest x-ray safety legislation.

Our applications lab reports "We are seeing increasing interest from protein scientists to use Dynamic Light Scattering (DLS) as a tool for determining the presence of aggregates as it is extremely sensitive to larger compounds. Also, DLS is creating quite a buzz because it provides these protein scientists with a simple, fast and non-destructive test, where the very sample can also be used for SAXS or SANS experiments. Small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS) are techniques used to extract structural parameters and determine the overall structures and shapes of biological macromolecules, complexes and assemblies in solution".
