Revision as of 14:20, 10 July 2006

Already measured with SP1.0 (I13534.pSB1A3)

  • Q04400.007 - mutated Q04400 (tetR QPI), point mutation in RBS. Works well, switches later than Q04400.

tetR QPI

  • Q04720 - mnt inverter, strong repressor - output not very high, and doesn't appear to be doing much (picture)
  • Q04730 - mnt inverter, weak repressor - output not very high, and doesn't appear to be doing much (picture)

Measured with older versions of screening plasmid (I13537.pSB1A3, I13538.pSB1A3, or I13534.pSB4A3)

  • Q04400 - Works reliably (quantitatively), switches at low input.
  • Q03400 - tetR inverter, weaker RBS driving tetR. Looks like it starts to switch, but very high GFP gives very high RFP numbers. Unclear what's happening.
  • Q01400 - tetR inverter, weakest RBS. Generally looks like it's stuck in the high-output stage. Some evidence suggests it might be switching, however.
  • Q01530 - p22 cII inverter. Appears to be stuck in the low-output stage, perhaps due to crosstalk with CW2553/lambda.
  • Q04530 - Same as Q01530, but with a stronger RBS driving the cII. Also stuck in low-output.
  • Q04740 - penI inverter with strongest RBS. Works well, switches at higher input than Q04400.
  • Q02740 - penI inverter, strong RBS. Looks like it begins to switch at high input.
  • Q03740 - penI inverter, medium strength RBS. Stuck on.

To be measured/constructed/etc

  • Q04400.007.Q04740/Q04740.Q04400.007 - possible bistable switch - having trouble getting it cloned in the first direction (tetR-penI) - weird stuff happening with growth rate and trying to prep the final plasmid, though colony PCR looks fine - load issues?
  • Q04510 - Ligated into the screening plasmid, but somehow missed being characterized. Seems unlikely to work, but hasn't been tested.
  • Q07400/Q08400/Q09400 - tetR inverters using RBS's from the Voigt lab. Not BB'd, and previous attempts were unsuccessful.
