Update

1. Digested the 10 hopefully mutagenized 30.BAT2.30.THI3 structures and ran on gel.

  • I am fairly confident that digest 9 worked. Digest 1 and 2 may have worked. Thus, I will PCR cleanup all three.

2. Ran the PMS PCR products on a gel and found that the only one with the correct band is the R tube. I will PCR cleanup that and put it into the metal blue holder labeled "PMSR cleaned up."

3. I am assuming that wells E10, E11, and E12 are the osmY.inverter.e0840 structures. I would say that they were moderately successful. At around stationary phase, fluorescence measurements on those wells leveled off, suggesting that no more GFP was being made in stationary phase^. However, for some reason overall GFP production was roughly twice as large as it was for the R0040 and osmY structures. We may want to keep an eye on this, but it seems as if we should move on and see how the osmY.inverter.xxxs and osmY.xxxs work with the GC. Some time next week, if I can be shown exactly what glycerols to use, I can redo everything at standard conditions (Jason gave me some hints). I will do samples of osmY.e0840 (Short and Long), R0040.e0840, TOP 10, and osmY.Inverter.e0840. Also, I need to know if the osmY.e0840s are on different backbones than the osmY.inverter.e0840s since Jason said this may make a difference. It may explain why there is twice as much GFP production in the osmy.inverter.e0840 structures.

^This actually makes a lot of sense since GFP is a very, very stable protein.
