ANTIBODY FORMULATIONS

摘要

This invention relates to a shear and temperature stable antibody formulations that are more stable than compared to a standard formulation (such as 30 mM citrate, 100 mM NaCl, pH 6.5). The present invention's shear and temperature stable antibody formulations show reduced precipitation when subjected to stress conditions but the standard formulation had aggregated. This result was unpredictable because thermodynamically the two formulations are similar as seen by their DSC (differential scanning calorimeter) profiles.
