- MMP-7 was present as a monomer and showed a value of 38 kDa or more.
- the above criteria are based on the accuracy of the measured value obtained by the dynamic light scattering method. If the value is more than a dimer, it is assumed that an obvious aggregate is formed, and a value smaller than that. In this case, it was a monomer.
- MMP-7 monomerization is performed by treating the MMP-7 aggregate with a monomerization solution.

Moreover, it can be read from the results of Example 2 (FIG. 2) that this effect is proportional to the concentration of calcium chloride. That is, by using a high concentration of calcium chloride, a greater effect of MMP-7 monomerization and maintenance of MMP-7 monomer can be expected. From the above, the concentration of the monovalent cation compound is 130 mM or less, preferably 100 mM or less, more preferably 80 mM or less, and most preferably 40 mM or less in the case of an aqueous solution. In addition, although it is not necessary to contain a monovalent cation compound, the inclusion is preferable from the viewpoint of quality as a pharmaceutical composition.

- proMMP-7-producing E. coli is prepared. Generally, it can be prepared by introducing proMMP-7 gene inserted into an expression vector into E. coli according to a conventional method. However, since proMMP-7 is highly toxic to E. coli, production efficiency may be extremely reduced. In order to solve this problem, devices such as adding a signal peptide to the N-terminal side of proMMP-7 are performed. In the case of proMMP-7, the expression level of proMMP-7 is increased by simply adding a signal peptide. In addition, a phenomenon that part of the expressed proMMP-7 is degraded by protease is observed.

(1)APSPを有するproMMP-7発現ベクター(pETMMP7)の構築
腎臓のcDNAライブラリー(HumanMTC Panel I, Catalog#: K1420-1, BD社)よりプライマーP1(配列番号1)とP2(配列番号2)を用いてproMMP-7遺伝子をPCRにより増幅した。増幅されたDNAをクローニングベクター(pCRII-TOPO, Invitrogen)に挿入し、得られたDNAの塩基配列を決定した。塩基配列の決定は、DNAシークエンサーを用いて行った。当該塩基配列とデーターベース(Accession Numbers: NM002423)に登録されているproMMP-7の塩基配列のホモロジー検索を行い、proMMP-7遺伝子が挿入されたプラスミド(pCRproMMP-7)を得た。
GeneTailor Site-Directed Mutagenesis System(Invitrogen社)を用い、添付のプロトコールに従って、上記(1)で得たpETMMP7のAPSP配列(Met-Lys-Gln-Ser-Thr-Ile-Ala-Leu-Ala-Leu-Leu-Pro-Leu-Leu-Phe-Thr-Pro-Val-Thr-Lys-Ala;配列番号8)のシグナルペプチダーゼ認識部位に変異を導入した(APSP配列で示されるアミノ酸配列の13番目のロイシン(Leu)をプロリン(Pro)に、21番目のアラニン(Ala)をグルタミン酸(Glu)に置換した)。APSPの改変には、5'側プライマーとしてM2(配列番号5)及び3'側プライマーとしてP6(配列番号6)の配列を用いた。得られた改変型APSPを有するpETMMP7(L13P-A21E)で大腸菌(BL21(DE3))を形質転換し、proMMP-7を発現する組み換え大腸菌(MMP7L13P-A21E菌)を得た。
