  • Publication number: 20230364020
    Abstract: The present invention provides formulations comprising polypeptides and hydroxypropyl methylcellulose acetate succinate (HPMCAS) derivatives. The formulations are stable; for example, during high temperature processing and in possible low pH environments. In addition, the HPMCAS derivatives provide protection to a pH sensitive protein against acidic degradation products from aqueous hydrolysis of poly(lactic-co-glycolic acid) (PLGA) in PLGA-based delivery systems.

  • Publication number: 20110052692
    Abstract: The present invention provides novel hydrogels and methods of making and using such hydrogels. The present invention provides hydrogels that may be formed by the self-assembly of peptides in solution. Such self-assembly may be brought about by a change in one or more characteristics of the solution. Characteristics of the solution that may be changed include pH, ionic strength, temperature, and concentration of one or more specific ions. In addition, hydrogels of the invention may be disassembled by changing one or more characteristic of the hydrogel such as pH, ionic strength, temperature, and concentration of one or more specific ions.
