The modern biosciences make many new proteins available. Nevertheless the handling of these proteins is quite difficult due to problems with their stability. This collection gives - in the form of tables - protein stability data for various temperatures and solvents. These data are most useful for the development of protein folding and the improvement of biotechnological stability for applications of proteins. Many biochemists, biotechnologists, food scientists and biophysicists work with proteins. They all have problems with the stability of proteins and thus difficulties in handling them. This data collection helps the scientist to choose the right temperature and appropriate solvent when dealing with a particular protein.
