  • Publication number: 20220282001
    Abstract: Present invention relates to the protection of peptides and proteins against aggregation. The process and compositions according to the invention improve protein stability in presence of cyclodextrins without establishing any covalent interactions, only by inclusion and/or electrostatic phenomena. The carbohydrate compositions provide a temporary local molecular coating on the surface of protein macromolecules, via physical glycosylation.
