A crucial part of any RBC lyophilization protocol is the primary drying temperature, which affects the sample drying rate and the dried cake's ability to form a stable glassy solid. Primary drying is most efficient just below the temperature...
As a partner of the European Virus Archive (EVA) FP7 project, our laboratory maintains a large collection of freeze-dried viruses. The distribution of these viruses to academic researchers, public health organizations and industry is one major aim of the EVA consortium. It is known that lyophilization requires appropriate stabilizers to prevent inactivation of the virus. However, few studies ha...
By using solid-state NMR spectroscopy, the integrity of the active center of alpha-chymotrypsin was investigated under a variety of nonaqueous conditions. Specifically, 13C cross-polarization/magic angle spinning NMR was used to analyze the ability of alpha-chymotrypsin to stabilize a transition state intermediate analog after freezing, drying, and addition of organic solvents (both anhydrous a...
