Abstract
Differential scanning calorimetric studies of protein solution provided the freezable water content as a function of concentration. Total water content was obtained by vacuum dehydration. The difference between the two gave the non-freezing water content in protein solutions. The values obtained by these techniques were 2–3 times larger than those obtained on the basis of NMR measurements on the same solutions.
