摘要: Over the past decades, nuclear magnetic resonance (NMR) spectroscopy has revealed itself to be an invaluable tool in areas of chemistry, biology and medicine. NMR, however, goes, far beyond this utilitarian role. Although a quantum mechanical phenomenon, its simplicity...

Protein solubility and stability depend on the co-solutes present. There is little theoretical basis for selection of suitable co-solutes. Some guidance is provided by the Hofmeister series, an empirical ordering of anions according to their effect on so
