> Freeze Drying > Excipients

OPS Diagnostics offers a number of excipients for use in freeze drying; each lot is tested and lyophilization certified. Excipients serve a dual purpose, to both provide bulk to a lyophilized sample and to stabilize biomolecules, particularly proteins. The disaccharides sucrose and trehalose are inert compounds that are traditionally used to stabilize samples during freeze drying. Mannitol, a sugar alcohol, is another common excipient with pharmaceutical applications.
