Forward primer’s last 5 3’ bases match to 7 locations. One of these forms a 600 bp product that is consistent with the lower band. Can extend the primer 5 bases to create a specific primer that only binds to its target site. -To grow more pOW1, prepared an overnight culture of PPY12 as Allison instructed the plasmid to be grown in yeast 6/23/18 -Talked with Dr. Glick -Indicated that cannot grow more plasmid in the PPY12 overnights as they need to be grown in bacteria -Transformed 1µL of remaining pOW1 plasmid into DH5α cells. Plated onto an LB+Amp plate (See below) -Created 20 LB+Amp plates following Glick lab plate recipe. Plated both my sample on 1 and a negative control on another. Did not have a strain that I knew had Amp resistance already, so I was unable to do a complete positive control. 6/24/18 -LB+ Amp Plate result -Negative control had no growth indicating the antibiotics are in sufficient quantity to kill non antibiotic resistant bacteria -pOW1 sample had too many colonies to count indicating a successful transformation was likely (Had no positive control, so cannot be fully certain until attempt to isolate the plasmid is performed) -Inoculated 5 overnight liquid cultures (4 for plasmid harvesting and one to make a glycerol stock and future positive Amp control) 6/25/18 -Miniprep Liquid cultures A→ D -Concentrations -A: 748.9 ng/µL -B: 573.3 ng/µL -C: 527.9 ng/µL D: 554.2 ng/µL -Made glycerol stock of Liquid culture E 6/26/18 -PCR amplified arg-ars sequence from pOW1 samples B-D -Want ~20 ng of the plasmid DNA (these dilutions result in pOW1 concentrations of 20 ng/µL) -A: 0.8µL pOW1 A, 29.2 µL H2O -B: 0.8µL pOW1 A, 23.0 µL H2O -C: 0.8µL pOW1 A, 21.1 µL H2O -D: 0.8µL pOW1 A, 22.2 µL H2O -Made glycerol stock of liquid pOW1 culture E -Gel electrophoresis of arg-ars pOW1 A-D PCR products -Lane 1: 1 Kb ladder; lane 2: pOW1 B; lane 4: pOW1 C; lane 6: pOW1 D -Ran at 110V for 30 minutes -Gel imaging showed only a smaller band around 100 bp for lane 2 (pOW1 sample B) -Suggests primer issue; will address in team meeting tomorrow -PCR amplified arg-ars sequences from pOW1 sample A -PCR amplification of pOW1 sample B side by side with CC -RF: followed previous PCR protocol, used arg-ars F1 and R1 primers -CC: Followed NEB Phusion protocol found on their website.

Indicates correct product synthesized -All gels showed banding below 500 bp. Likely a combination of mispriming and Remaining primer as it is extremely faint. -Overall impression: Desired product can be synthesized at a range of temperatures using standard protocols. Issues with cloning likely have been technique related or a problem with the dNTP stock as it was homemade. Using the new dNTP from NEB yielded correct results. -Gel Purification of all 12 fragments -Purification of ArgArs -Followed Promega protocol for Wizard PCR cleanup. Yields were less than 10 ng/µL and 260/230 was 0.03 avg. Discarded samples. Likely due to improper incubation with membrane binding solution (See reasoning below) -Purification of Gradient products -Done with RF and VP -Followed directions according to promega protocol. Measured concentrations were 30-56 ng/µL with 260/230 of 0.46. Still not great, but might be able to improve on future runs. Suspect incubation with the membrane binding solution is too low and DNA does not have sufficient time to bind to column. Could also be a problem with adding the membrane binding solution as this was a problem in my lab with the Zymo Kit.

-0.1µL of Btg1
-Produces 1 fragment in pSD000 and 2 fragments in pSD001
-Incubated diagnostic digests in 37ºC incubator for one hour
-Imaging the gel showed none of the samples to be consistent with what we would expect for pSD001
-All of the bands were the same size indicating that pSD001 was not successfully made
-Gibson reaction was unsuccessful, YM-RFP was not inserted
-Gel Purification failed, ran gel, no bands appeared
-Prepared new gel following
-New lab meeting notes
-Run the gel for longer
-Something expired last July, we should get more of it
-PCRs have had some changes
-Primers modified to prevent primer dimers
-HS never responded
-Should we contact Northwestern??
-We PCRd the lux operon fragment
