摘要 |
An objective of the present invention is to provide aqueous preparations comprising eMIP, a derivative of macrophage inflammatory protein 1α(MIP-1α) which has an immunopotentiation activity, and stabilizer(s). The present inventors conducted dedicated studies to achieve the above-described objective. As a result, the present inventors discovered that eMIP degradation is suppressed by addition of at least one or more additives selected from sodium chloride, L-histidine, L-arginine, L-arginine hydrochloride, L-lysine hydrochloride, citric acid, and sodium edetate (EDTA). Furthermore, the present inventors demonstrated that phosphate buffer of pH 5 to pH 7 is a preferable pH adjuster for the aqueous eMIP preparations of the present invention.
