Applications of BBa_K917005
Expression of this biobrick inhibits growth of cells in the presence of nitro drugs such as metronidazole. We have rigorously tested this biobrick's potential as a counter-selectable marker in its pre-biobrick form (in Blue script vector with lac promoter).Although growth of cells containing nitroreductase is inhibited in plates, it is not absolute and therefore unsuitable for couter-selection.
Nitroreductase containing cells's growth (right) is markedly inhibited in comparison to control cells (left) at 90 ug/ml metronidazole. However, this inhibition is not absolute so cannot be used for counterselection.
Aerobic liquid culture results are more promising with profound growth inhibition of nitroteductase-containing cells while control cells are growing.
Liquid aerobic cultures of BS-nitroreductase and BS-control in the presence and absence of metronidazole. At 150 ug/ml metronidazole, cells which contain nitroreductase show almost no growth.The measurements were made in triplicate. Error bars are standard error of the mean. Inital OD600 (just after inoculation) was subtracted.
