PROBLEM TO BE SOLVED: To provide a stabilized antibody-containing preparation with low loss of active ingredients even after long-term storage.SOLUTION: The stabilized preparation contains an antibody in a glycine buffer solution and/or a histidine buffer solution. A process for producing the stabilized protein-containing preparation is provided in which the pH value is controlled with the use of a basic amino acid, a basic amino acid derivative, or a salt thereof.COPYRIGHT: (C)2012,JPO&INPIT【課題】長期保存した後も活性成分の損失が少ない、安定化させた抗体含有製剤の提供。【解決手段】グリシン緩衝液及び/又はヒスチジン緩衝液中に抗体を含んでなる安定化製剤の提供。さらに、塩基性アミノ酸又は塩基性アミノ酸誘導体、又はその塩を用いてpH調整を行うことを特徴とするタンパク質含有安定化製剤の製造方法を提供する。【選択図】図2
