Disclosed herein are methods for improving a parameter of a protein-related process comprising providing a viscosity-reducing excipient compound selected from the group consisting of hindered amines, aromatics and anionic aromatics, functionalized amino acids, oligopeptides, short-chain organic acids, low molecular weight aliphatic polyacids, diones and sulfones, zwitterionic excipients, and crowding agents with hydrogen bonding elements, and adding a viscosity-reducing amount of the viscosity-reducing excipient compound to a carrier solution for the protein-related process, wherein the carrier solution contains a protein of interest, and carrier solutions comprising a liquid medium in which is dissolved a protein of interest, and a viscosity-reducing excipient, wherein the viscosity of the carrier solution has a lower viscosity that that of a control solution that is substantially similar to the carrier solution except for the presence of the viscosity-reducing excipient. |
