An improved vector for chromosomally-integrated promoter-lux fusions is described. The modified vector was tested in parallel with the unmodified vector using the well-characterized Escherichia coli araBAD promoter in the Pseudomonas aeruginosa attTn7 site. The modified mini-Tn7 showed reduced background luminescence, and increased luminescence upon induction, giving >16-fold higher induction ratio.
描述了一种用于染色体整合型启动子 - 荧光素酶融合的改进载体。使用特征明确的大肠杆菌araBAD启动子,在铜绿假单胞菌attTn7位点将修饰后的载体与未修饰的载体进行平行测试。修饰后的mini-Tn7显示背景发光降低,诱导后发光增加,诱导比提高了16倍以上。
