A) Growth curve shows that WT grows slightly faster than strains bearing plasmids. B) Per cent of population above fluorescence threshold. None of the WT cells were fluorescent, almost all of the -lacI:LVA cells were constitutively fluorescent, and only cells overexpressing LacI:LVA weren’t fluorescent when not induced. Upon induction increasingly per cent of +lacI:LVA became fluorescent and reaches a maximum of 70-75 per cent after 90 min. C) Mean GFP fluorescence of entire population. The -lacI:LVA cells became increasingly more fluorescent over time, both with and without induction. Though, the induced cells were slightly more fluorescent, which is probably because of the relief of repression from LacI naturally present in the cells. For the +lacI:LVA cells the results from B is reflected. | A) Growth curve shows that WT grows slightly faster than strains bearing plasmids. B) Per cent of population above fluorescence threshold.

FACS results and growth curves of +/-lacI:LVA carrying strains. One triplicate of MG1655 (WT) and two triplicates of MG1655 strains carrying either BBa_K1088008 (-lacI:LVA) or BBa_K1088009 (+lacI:LVA) were grown from OD600 0.005 to approximately 0.2. At this OD the MG1655 triplicate and one triplicate of each strain carrying constructs were induced with 1 mM IPTG at time 0 min. FACS measurements were done at times: -30, 0, 30, 60, 90, 120, and 150 min. A) Growth curve shows that WT grows slightly faster than strains bearing plasmids. B) Per cent of population above fluorescence threshold. None of the WT cells were fluorescent, almost all of the -lacI:LVA cells were constitutively fluorescent, and only cells overexpressing LacI:LVA weren’t fluorescent when not induced. Upon induction increasingly per cent of +lacI:LVA became fluorescent and reaches a maximum of 70-75 per cent after 90 min. C) Mean GFP fluorescence of entire population. The -lacI:LVA cells became increasingly more fluorescent over time, both with and without induction. Though, the induced cells were slightly more fluorescent, which is probably because of the relief of repression from LacI naturally present in the cells. For the +lacI:LVA cells the results from B is reflected. |
Jasonk 15:15, 26 July 2006 (EDT):The LVA degradation tag leads to rapid degradation and as a result seeing significant repression with C0012 is unlikely. BBa_C0013 is a lacI with no LVA tail (though at the moment it is not constructed).
