the single red colony on a plate (probably got mixed with some white colony) from Q04740 in SP1.0 glycerol - got high RFP signal and GFP tracked induction - streaked this culture for July 11 testing
one white colony from the same plate - GFP showed this time - background RFP
empty SP1.0 - showed GFP and RFP
July 11, 2006
Colony PCR of Q04740 colonies, E0040F-E1010R. Two red and two white colonies. Region should be ~1.6 kb. Red colonies ~3 kb (transposable element jumped in). White colonies ~1.6 kb.
grew to stationary, then diluted back 100x, grew for ~8 hrs (cultures were all very light except for the empty SP and Q04400.007), innoculated at ~11:30 p.m.
clones from July 6's penI red no induction culture, streaked on plate:
Q04740 red colony #1 (C) - innoculated at 0.0001 - grew ~14.5 hrs (picture)
Q04740 white (pink) colony #4 (D) - innoculated at 0.0001 - grew ~14.5 hrs (picture)
sequencing results: red colony had IS5 element jump in after the hairpin / before the prefix; white colony, when grown up/prepped/sequenced had a population with the insertion element in the same spot and a population without IS5
three 50 ul PCR reactions: (note, I goofed, meant to do 4x these amts so I could cover low-med-high mutation frequencies but forgot to take the vector into account)
~188 ng target DNA (medium range mutation freq)
~75 ng target DNA (medium range mutation freq)
~12.5 ng target DNA (high range mutation freq)
PCR cleanup
Day 1.5 (July 17): restriction digest
did overnight double digest (XP) on PCR reactions
Day 2 (July 18): ligation and transformation
ran digest on a gel, did gel extraction - eluted into 30 ul EB total
performed a 40-ul ligation reaction using all of the high range mut freq digest + 1 ul cut SP1.0
dialyzed - after dialysis, total volume was 13 ul
used 6 ul for a transformation that arced
used 3 ul for a transformation that worked (~4 ul left over)
dialyzed 40 ul of positive control (2 ng/ul?) - took 1 ul of the diaylzed plasmid and transformed it
did a negative control electroporation with CW2553/pJat8
grew in 1 mL SOB for 1.25 hrs
plated 50 ul (1:20) of the experimental (AG), positive control (Amp, could have used AG in CW2553/pJat8), and negative control (AG) on antiobiotic plates
plated 1:1e7 of expt'l and controls on LB only
put the rest of the transformation 1 mL - 65 ul into 9 mL of supplemented M9 in baffled flasks around 7:30 or 8 p.m.
put plates in the warm room around 9 p.m.
Day 3 (July 19): arabinose induction
the 10 ml culture grew ~15-16 hours overnight: end OD = 0.27
set up 25 ml experimental cultures at 0% and 1e-4% arabinose
added 1 ml or 0.5 ml of overnight (4 flasks total)
plate results:
+ control:
1:1e7 dilution on LB only = 11 colonies
1:20 dilution on LB+AG = lawn of cells --> replate with a 1:1e5 , 1:1e4
- control:
1:1e7 on LB only = no colonies --> replate 1:1e5, 1:1e4
1:20 on LB+AG = no colonies
Q04720 library:
1:1e7 on LB only = no colonies on LB only --> replate at 1:1e5, 1:1e4
1:20 on LB+AG = 1 colony
Day 4 (July 20): MOFLO
ran the no induction library culture on the MoFlo
forgot about the high induction culture (ooops)
replating results:
+ control: 1 colony on LB+AG at 1:1e4 dilution, none at 1:1e5 dilution
- control: no colonies on LB only at 1e4 or 1e5
Q04720 library: no colonies on LB only at 1e4 or 1e5

since none of the libraries were very big, just took 1 mL of the overnight (grew ~15 hrs) and put on ice for the MOFLO
Day 4 (July 27): MOFLO
ran all 7 libraries (no induction) and collected data (picture)
sorted Q04400 (200 cells) and mnt A (150 cells) for high RFP into 1 mL M9
put in 5 ml M9+AG, grew for >48 hrs (got very dense), and made 1 glycerol of each
Day 5 (August 6): second-round induction
thawed glycerols, spun down, aspirated media, and added to 10 ml M9+AG
mnt A = 0.33 (made 1 glycerol, labeled L.Q04720C.1)
innoculated 25 ml of M9+AG at 0% and 1e-4% arabinose with 20 ul of each culture (4 cultures total)
Day 6 (August 7): harvest
Q04400: grew ~17 hrs, harvested 1 ml & put on ice
0% final OD = 0.06
1e-4% final OD = 0.07
mnt A: grew ~12 hrs, harvested 1 ml & put on ice
0% final OD = 0.41
1e-4% final OD = 0.42
Day 7 (August 8): MoFlo
looked at libraries under no induction again (see how well it sorted last time) and under 1e-4% arabinose, didn't sort (picture)
July 27, 2006: ligation controls
(+) control:
1 ng straight electroporation (diluted in MilliQ H20)
20 ul "ligation" with 12 ng of pUC18 DNA and 1 unit (1:400 dilution) of T4 DNA ligase (2 hrs)

20 ul "ligation" with 12 ng of DNA and no ligase (2 hrs)
20 ul ligation with 12 ng of DNA and 10 units (1:40 dilution) of T4 DNA ligase (2 hrs)
20 ul ligation with 12 ng of DNA and 1 unit of T4 DNA ligase (30 mins, 1 hr, 2 hrs)

SP1.0 vector from an XP digest that was extracted using Qiaex II kit (nanodrop gave ~9.3 ng/ul)
used 2.3 ul insert and 6.7 ul vector for every ligation, which is maybe ~6:1 ratio insert:vector, ~100 ng DNA total
20 ul ligation with ~100 ng DNA and 1 unit of T4 DNA ligase (30 mins, 1 hr, 2 hrs)

Transformation
put on ice after electroporation for a few minutes before moving to 37 C, as per Knight lab protocol

made 3 glycerols of both of Reshma's QPI libraries from the overnight cultures (labeled L.C2002.0 and L.C2003.0, note: not part names, names of the repressor protein)
spun down overnight cultures, aspirate off SOC/M9 media, resuspend in 10 ml M9, took OD's:

Q04720#2 = 0.43
C2002 QPI = 0.42

added 1 ml of resuspension to 10 ml M9+AG (should be more than enough cells to cover our library size at this OD)
grew ~7-8 hrs, took OD's:

innoculated 25 ml M9+AG at 0% and 1e-4% arabinose with 50 ul of each culture

5 p.m.
sequencing of Q04740 in SP1.0 colony#1 all came up OK (VF2, VR, E0040F, E0040R, E1010F, E1010R)
a point mutation present in pSB1A2 backbone (pMB1 replication origin)--also showed up in sequencing for I14103 and all other times I sequenced Q04740 in SP1.0 with E1010F--probably came from a stock of SP1.0--don't know if this affects anything
sorted L.Q04400.1.0 for high in/low out --> L.Q04400.1.0.1

made 1 glycerol: L.Q04400.1.0.1
added 1.4e6 cells to 25ml experimental cultures (0%, 1e-4%)
August 28, 2006: Reshma's promoter libraries
double-stranded library oligos (25 pmol each)
L.RS.P8
L.RS.P9
L.RS.R2000
saved 1 ul (out of 100 ul PCR reaction) for gel analysis Error creating thumbnail: File missing1ul of PCR reaction compared next to 1ul of 1:40 dilution of original single-stranded library (lanes alternate)
PCR cleaned the rest into 30 ul EB
Restriction Digests (August 29)
20min, 37 C restriction digests on libraries (XP), heat inactivation
PCR cleanup & elution into 30ul
L.RS.P8 = 42.1ng/ul * 30ul
L.RS.P9 = 41.5ng/ul * 30ul
L.RS.R2000 = 39.6ng/ul * 30ul
backbones from August 09: cut SP
B0032.C2002.B0015 in SP1.0 = 319.9ng/ul * 30ul
B0030.C2003.B0015 in SP1.0 = 300.5ng/ul * 30ul
used 1ul of these samples for gel analysis
Ligation
6 ligation reactions with 8.5ul insert + 8.5ul vector
undiluted ligase (1ul) in 20ul reaction volume
messed up with L.RS.P8 into C2002 backbone reaction --> had to bump up the volume to 47ul, but there's still just 1ul ligase
30min rm temp incubation, heat inactivation
save 1ul for gel analysis
dialysis 30min
Error creating thumbnail: File missingcomparisons of restriction digests, ligations, and dialyzed ligations (1ul volumes of each); left to right: C2002 backbone (SP), C2003 backbone (SP), P8 libary (XP), P9 library (XP), R2000 library (XP), P8/C2002 ligation, P8/C2002 dialysis, P9/C2002 ligation, P9/C2002 dialysis, R2000/C2002 ligation, R2000/C2002 dialysis, P8/C2003 ligation, P8/C2003 dialysis, P9/C2003 ligation, P9/C2003 dialysis, R2000/C2003 ligation, R2000/C2003 dialysisError creating thumbnail: File missingsame gel with longer UV exposure to help see the insert better
Transformation
electroporated 3ul, except for the one I messed up, did 6.3ul for that one
on ice, then incubate at 37 C for 1hr
plated:
LB+AG 1:40 dilution (25ul of transformation directly)
LB only 1:1e6 dilution
added 10ml M9+AG, grew overnight ~12.5 hrs
