3) The RFP needs a while to show up, so it turns out that the larger colonies tend to be red (light red), and the smaller whites, so I picked all the wrong colonies last week it is also suspect because Prof. Anderson said I have a suspiciously small number of white colonies. Repick 4 colonies (white this time) and put into new spec+broth tubes

4) Zach picked 3 more colonies from my 2 plates; of those 1 grew. Out of the 7 tubes (4 from me, 3 from Zach) 3 had significant growth (the other ones looked either dead or very slow growing); Do Mini prep (plasmid extraction) from the 3 that worked
protocol:
- Pellet 2 mL saturated culture by spinning full speed, 30 seconds in a 2mL Microcentrifuge tube.
- Dump supernatant
- Add 250uL of P1 buffer into each tube. Resuspend the cells thoroughly
- Add 250uL of P2 buffer (a base that denatures everything and causes cells to lyse). Gently mix up and down. Solution should become clearer.
- Add 350uL of N3 buffer (an acid of pH ~5 that causes cell junk - including protein and chromosomal DNA - to precipitate, and leaves plasmids and other small molecules in solution). Slowly invert a few times, then shake.
- Spin in centrifuge at top speed for 5 minutes.
- Label blue columns with an alcohol-resistant lab pen.
- Pour liquid into columns, and place the columns into the centrifuge. Spin at full speed for 15 seconds.
- Dump liquid out of the collectors under the columns (the DNA should be stuck to the white resin)
- Wash each column with 500 uL of PB buffer.
- Spin in centrifuge at full speed for 15 seconds, then flick out the liquid again.
- Wash with 750uL of PE buffer (washes the salts off the resins).
- Spin in centrifuge at full speed for 15 seconds and flick out liquid again.
- Spin in centrifuge at full speed for 90 sec to dry off all water and ethanol.
- Label new Microcentrifuge tubes and put columns in them.
- Elute them by adding 50uL of water down the middle of the column (don't let it stick to the sides).
- Spin in centrifuge at top speed for 30 seconds.
- Take out columns and cap the tubes.
***in practice tubes are labeled "Au D Ec1 sbb1208 leu" on top and "AuD Ec1 sbb1208 leu 3/1/2012" on the side; simiarly for strains Ec2 and Ec3

2) Digest plasmids extracted from E coli yesterday (Ec1, Ec2, Ec3) and the parent plasmid pBca9525-Bca1834
Analysis: Digestion of parent vector pBca9525-Bca1834 with NheI/BamHI will yield: 3494+841 Digestion of good plasmid with NheI/BamHI will yield: 3494+142 (actually a bit less) Conclusion: The difference between parent and 'good' plasmids should be readily distinguishable on a gel when the plasmids are digested by NheI/BamHI
Protocol for Digestion : Note: this is adjusted for high copy number plasmids such as pBca9525
For Ec1, Ec2, Ec3 6uL ddH2O 2uL Miniprepped plasmid 1uL 10x NEB Buffer 2 .5uL NheI .5uL BamHI
For pBca9525-Bca1834 (aka "K" in the tube, for 'control') 7uL ddH2O 1uL Miniprepped plasmid 1uL 10x NEB Buffer 2 .5uL NheI .5uL BamHI
- Incubate at 37 on the thermocycler for 60 minutes
- In practice, tubes were labeled "Ec1" on top and "3/2/2012" on side, simiarlly for Ec2, Ec3 and K (K=control=parent plasmid)
NOTE: There was not enough time and gels to run the digested plasmids on a gel on the same day. Since these digestions will just be used for mapping (we send in the entire miniprepped plasmids for sequencing), freezing these samples and running them on a gel Monday should be okay (confirmed with Zach)

1) Do Zymo cleanup (regular, not small fragment) on SOE3
PCR ca998/g00101 on A+B (1451bp, pcrpdt)
protocol used for setup:
- Add 180 uL of Zymo ADB buffer (brown bottle) to a 33uL or 50uL reaction.
- Transfer into the Zymo column (small clear guys)
- spin through, discard waste.
- Add 200 uL of Zymo Wash Buffer (which is basically 70% ethanol)
- spin through, discard waste.
- Add 200 uL of Zymo Wash Buffer
- spin through, discard waste.
- spin for 90 seconds, full speed to dry.
- elute with water into a fresh Eppendorf tube, use the same volume of water as the volume of the original reaction

2) Run Digested plasmids on gel along with parent vector digest control
Analysis: Digestion of parent vector pBca9525-Bca1834 with NheI/BamHI will yield: 3494+841 Digestion of good plasmid with NheI/BamHI will yield: 3494+142 (actually a bit less) Conclusion: The difference between parent and 'good' plasmids should be readily distinguishable on a gel when the plasmids are digested by NheI/BamHI
3) Rerun PCA2 product (from 2/21/2012, has been zymo cleaned)to check size (since the previous gel had a ugly ladder)
Discussion: the size looks a little bit bigger than 100bp, but I'm expecting (~140bp). Zach says the band might be 140bp anyways

4) Do plasmid extraction/mini prep for the 4 strains Zack picked over the weekend
NOTES: Out of the 4 tubes, Tubes 2-4 are a pale cream color while the strain in tube 1 is noticably more yellow Even after pelleting, the media in tube 1 was more yellow than the other 3 Tube 4's pellet had some reddish looking swirls in the center of the pellet....
protocol used for setup:
1. Pellet 2 mL saturated culture by spinning full speed, 30 seconds in a 2mL Microcentrifuge tube. 2. Dump supernatant 3. Add 250uL of P1 buffer into each tube. Resuspend the cells thoroughly 4. Add 250uL of P2 buffer (a base that denatures everything and causes cells to lyse). Gently mix up and down. Solution should become clearer. 5. Add 350uL of N3 buffer (an acid of pH ~5 that causes cell junk - including protein and chromosomal DNA - to precipitate, and leaves plasmids and other small molecules in solution). Slowly invert a few times, then shake. 6. Spin in centrifuge at top speed for 5 minutes. 7. Label blue columns with an alcohol-resistant lab pen. 8. Pour liquid into columns, and place the columns into the centrifuge. Spin at full speed for 15 seconds. 9. Dump liquid out of the collectors under the columns (the DNA should be stuck to the white resin) 10. Wash each column with 500 uL of PB buffer. 11. Spin in centrifuge at full speed for 15 seconds, then flick out the liquid again. 12. Wash with 750uL of PE buffer (washes the salts off the resins). 13. Spin in centrifuge at full speed for 15 seconds and flick out liquid again. 14. Spin in centrifuge at full speed for 90 sec to dry off all water and ethanol. 15. Label new Microcentrifuge tubes and put columns in them. 16. Elute them by adding 50uL of water down the middle of the column (don't let it stick to the sides). 17. Spin in centrifuge at top speed for 30 seconds. 18. Take out columns and cap the tubes.

1) Digest plasmids extracted from E coli last Thursday and the parent plasmid pBca9525-Bca1834
Analysis: Digestion of parent vector pBca9525-Bca1834 with EcoRI/BamHI will yield: 2473+1863 Digestion of good plasmid with EcoRI/BamHI will yield: 2473+1451bp (although the SOE-PCR on the gel shows up as nearly 3kb) Conclusion: The difference between parent and 'good' plasmids are not readily distinguishable on a gel when the plasmids are digested by EcoRI/BamHI ....unless I get the ~3kb size I saw as the digested SOE product.
Digestion of parent vector with BamHI/NotI will yield 3754 (there should be no NotI site in the parent vector) Digestion of good plasmid with BamHI/NotI will yield 3481+273 But it doesn't look like we have NotI
Protocol for Digestion : Note: this is adjusted for high copy number plasmids such as pBca9525, also digested parent plasmid pBca9525-Bca1834 as a control for the gel
For tra1, tra2, tra3 7uL ddH2O 1uL Miniprepped plasmid 1uL 10x NEB Buffer 2 .5uL EcoRI .5uL BamHI
2) Run digested plasmids (4 samples, 1 control) on gel
I have 3 bands, but that's explainable with partial digestion of the plasmids. The important part is that my plasmids look different from the control. What's also interesting to note is the lowest band looks like it could plausibly be 1.4kb, my expected size for the part (and SOE-PCR product) that I never go when I was doing the SOE-PCR (I kept getting something that looked ~3kb).
3) Load into Professor's storage plates 2 out of the 4 plasmids, #2 and #3 (randomly chosen).
These plasmids will be sent out for sequencing, eventually, and I'll analyze them.

All exhibited the correct phenotype except for FKBP (experimental plasmid; should have been white without B/B, but were green on both B/B and non B/B plates) and FtoxR (no colonies on B/B plate and ~6 colonies on non B/B plate) - it's possible that the FKBP results were due to cross contamination on the plasmid plate (there was condensation/liquid on the top of the wells/cover) so we will retransform
