Excipient compounds for biopolymer formulations
The invention encompasses formulations and methods for the production thereof that permit the delivery of concentrated protein solutions. The inventive methods can yield a lower viscosity liquid protein formulation or a higher concentration of therapeutic or nontherapeutic proteins in the liquid formulation, as compared to traditional protein solutions. The inventive methods can also yield a higher stability of a liquid protein formulation.
