中文摘要:依据毛细管气相色谱法灵敏度高 ,样品用量少 ,分辨率高的特点 ,建立了一个用于检测棉铃虫Helicoverpaarmigera幼虫中肠和脂肪体细胞色素P450 O-脱甲基活性产物的小型反应体系 (875μL) ,其中含 0.1mol /L ,pH 7.8Tris-HCl缓冲液 ,0.5μmol,NADPH ,7.5 μmolMgCl2
英文摘要:A 875μL of reaction system determining the activity of p-nitroanisole O-demethylation by cytochrome p450 was developed based on the traits of the capillary gas chromatography(CGC), which has higher sensitivity, less sample volume and higher resolu
