The Use of Disaccharides in Inhibiting Enzymatic Activity Loss and Secondary Structure Changes in Freeze-Dried β-Galactosidase during Storage


The purpose of this study is to show how disaccharides differ in their ability to protect lyophilized β-galactosidase from enzymatic activity loss and secondary structure changes during storage. β-galactosidase was lyophilized with trehalose, sucrose, cellobiose or melibiose at 2:1, 20:1 and 40:1 excipient/protein weight ratios, and stored up to 90 days at… (More)
