However the Espf7 was gene engineering strain of DCase's genes cloned in E.coli.DCase expressed by Espf7 could transform NC-D-pHPG into D-pHPG.But DCase was in cell membrance,Dialysing cell membrance was investigated.

此外还有一菌种Espf7是克隆了DCase基因的大肠杆菌,它能表达DCase活性继续将NC-D-pHPG转化为D-pHPG,可DCase是胞内酶,故需要对其进行细胞破碎才能释放出酶。

PUC19 plasmid were successfully enriched and purified from the E. coli DH5α under the magnetic fields. The obtained plasmid retained native the bioactivity to be used for restriction enzyme digestions and cell transformations.

用这种方法成功地从大肠杆菌DH5α浓缩和纯化得到了pUC19质粒,该质粒具有生物活性,可直接用于限制性酶切和细胞转化等分子生物学下游操作。

METHODS: The rhBMP-2,expressed in Escherichia coli, was washed by Triton X- 100 and further purified by DEAE chromatography.The inclusion bodies were resolved in 8 mol/L urea, and were refolded and dimerized in the redox systems (reduced and oxidized glutathione). Finally, a one - step purification procedure based on the heparin affinity chromatography was implemented. The biological activity of purified rhBMP - 2 were tested by induction of the alkaline phosphatase activity in C2C12 cells.

大肠杆菌中通过温度诱导表达重组人骨形成蛋白-2经过Triton X-100清洗之后,又通过DEAE离子交换层析纯化包涵体,包涵体在8 mol/L尿素变性溶解,在氧化-还原(还原型和氧化型谷胱甘肽)复性系统中,通过简单的稀释复性,通过肝素亲和层析一步纯化法纯化重组人骨形成蛋白-2,最后通过诱导C2C12细胞产生碱性磷酸酶检测重组人骨形成蛋白-2活性。
