AQUEOUS SOLUTION CONTAINING A PROTEIN AND ANIONIC POLYMER OR SALT AND METHOD OF INCREASING THE PROTEIN CONCENTRATION OF AN AQUEOUS SOLUTION

摘要

Aqueous protein-containing solutions, in which a protein is dissolved at a high concentration at a pH near the isoelectric point of the protein by adding an anionic polymer or a salt thereof to the solution. Pharmaceutical formulations using a physiologically active protein are prepared using this technique.
