BChE的音标

Methods The condensation of 2-bromo-5,6-dimethoxy-indan-1-one with various aminoalkyl phenols in the presence of ( K_ ( 2) CO_ ( 3)) and acetonitrile gave the corresponding title compounds, and the in vitro AchE and BchE inhibitory activities were evaluated by the modified Ellman method.

方法在K2CO3和乙腈存在下，将2-溴-5,6-二甲氧基-1-茚酮与多种胺烷基苯酚缩合得到一系列苯氧茚酮类衍生物，并采用改进的Ellman方法研究它们的体外AchE和BchE抑制活性。

The BChE was purified to electrophoretic homogeneity by salting out, ion-exchange chromatography on DEAE-cellulose and gel filtration on Sephadex G-200. Finally the enzyme was purified 278. 5 folds and the enzyme activity recovery ratio was 17.8%.

该酶经过两次硫酸铵盐析、DEAE-52离子交换层析和Sephadex G-200凝胶过滤层析后，其比活力由21.5U/mg提高到5944.1U/mg，纯化278.5倍，回收率为17.8%，达到电泳纯。

A BChE from A serum was selected to determinate pesticide residues by comparison of many BChE from different materials.

通过对6种不同动物组织的胆碱酯酶的比较研究，最终选择以A血清BChE作为农药残留的检测用酶。
