背景資料

Matrix metalloproteinase-7（MMP-7) also known as matrilysin and PUMP（EC 3.4.24.23) cleaves a number of substrates including collagen types IV and X， elastin， fibronectin， gelatin， laminin and proteoglycans. MMP-7 is closely related to the stromelysin family members but is encoded by a different gene. MMP-7 is the smallest of all the MMPs consisting of a pro-peptide domain and a catalytic domain. It lacks the hemopexin-like domain common to other members of the MMPs. MMP-7 is secreted as a 28 kDa proenzyme and can be activated in vitro by organomercurials and trypsin and in vivo by MMP-3 to a 18 kDa active MMP-7 enzyme. Once activated， MMP-7 can activate pro-MMP-1 and pro-MMP-9 but not pro-MMP-2. MMP-7 is widely expressed having been reported in elevated levels in cycling endometrium as well as in colorectal cancers and adenomas， hepatocellular carcinomas， rectal carcinomas， and approximately 50% of gliomas.

溶解建議

提供的人基質(zhì)金屬蛋白酶-7（MMP 7）產(chǎn)品為滅菌的透明溶液；其中人基質(zhì)金屬蛋白酶-7（MMP 7）產(chǎn)品溶解于10mM HEPES（pH 7.4)， 5mM CaCl2，150mM NaCl溶液中.

保存建議

人基質(zhì)金屬蛋白酶-7（MMP 7）溶液可以在4℃冷藏保存3周；如果想延長保存時間，建議分裝后置于-18℃凍存.請避免反復(fù)凍融.

其他

ProSpec 是一家全球著名細(xì)胞因子蛋白生產(chǎn)和研發(fā)的公司，具有20多年的生產(chǎn)經(jīng)驗，專注于蛋白（重組及合成）生產(chǎn)研發(fā)。我們的核心產(chǎn)品包括：干擾素、白介素、骨蛋白、腫瘤壞死因子、成纖維生長因子、瘦素、干細(xì)胞因子、催乳素、表皮生長因子、胰島素樣生長因子、神經(jīng)生長因子、集落刺激因子、激素、酶、病毒抗原以及各種重組蛋白等。 的生產(chǎn)工藝和規(guī)模使其可以提供毫克到克級蛋白，價格優(yōu)于同類公司。絕大部分產(chǎn)品是天然成熟型蛋白，而不含有標(biāo)簽蛋白。考慮到大部分研究者希望能更靈活地配制蛋白溶液，ProSpec-Tany絕大部分產(chǎn)品沒有添加保護劑或鹽，這就對工藝提出了更高的要求。同時，ProSpec-Tany絕大部分產(chǎn)品為凍干粉，因此易于運輸和保存。
