2020-04-22 11:29 Disulfide bridges, also called disulfide bonds, and free sulfhydryl groups are essential for biopharmaceutical products. The number and position of disulfide bridges are required for obtaining the correctly folded structure and biological function of the proteins. Thus disulfide bridges are crucial for quality control in biopharmaceuticals and the ICH Q6B Guidelines requires the accurate information of the number and position of disulfide bridges. Disulfide bridges analysis from Pronalyse helps you identify and quantify disulfide bridges and sulfhydryl groups.
