Thursday, 5/19/16
Miniprep pSMART and yib
Used a 30 mL elution
Tested the concentration using UV/Absorbance and found that at 280 nm, the tib had an absorbance of 0.006 and at 260 nm it had an absorbance of 0.019. Using the ratio of Abs 1= 50 ug/mL this leads to the tib miniprep resulting in DNA of a concentration 95 ug/mL. The pSMART had an absorbance of 0.0037 at 260 nm and an absorbance of 0.025 at 280 nm. the ratio of 260:280 of 1.48. This leads to a concentration of 135 ug/mL.

Used 1 uL of vector; 5 uL of mix, and 1.5 uL of inserts
Transformations of Gibsons
Used 3 uL of DNA; 20 uL of Comp Cells
Recovered for 2-3 hours
All samples electroporated for 654 ms at around 1600 V

Colony PCR Protocol
Inoculation of E. cloni (Parth; Nisa)
Inoculated a colony of E. cloni in 35 uL of LB broth
Tuesday, 5/24/16
Ran Gels on 5/19 Gibsons
8 ul of ladder; 2 ul of DNA stain; 10 ul of DNA; 160 V for 20 min
There were no discernible bands; results do not align with expected transformation success
Cause is unknown as there were numerous colonies on plate but no inserts detectd
Because the mini prepped positive control clearly worked, hypothesis is that the econoTaq master mix is not successfully breaking down the cells to allow the DNA inside the nucleus to replicate.
Colony PCR of Gibsons from 5/23 (Ben; Emma)
8 colonies were celected from each plate except BadA
Made LB tubes with 50 mL of KAN + LB
Protocol:
●
Colony PCR Protocol

Left overnight in incubator at 37 C
Electroporation Results:
●
T1: 250 V; 654 ms
●
T2: 1690 V; 654 ms
●
T3: 660 V; 654 ms
Wednesday, 5/25/16
Ran Gels for Colony PCR from 5/24
Protocol:
●
Gels
Used 10 uL of DNA instead of 5 uL of H20 and 5 uL of DNA
The Controls were diluted with 7uL of H2O in order to have enough to use in every gel (there was only 25 uL available after the PCR). The controls were also diluted by H2O in each well (5 uL of DNA and 5 uL of H2O). Controls were yibDp-GFP (+) and pSmart, no insert (-)
Two sets of three Gels ran for 35 min at 160 V
Note: Controls seemed to be the flipped version of what was expected. Assumed that controls were mislabeled
DNA PCR (Emma; Thomas)
Goal: To determine if the Gibsons worked; Is the Colony PCR lysing the cells enough?
Used Colony PCR protocol but added 1 uL of DNA instead of 1 colony
For BadA, 2 uL of dH2O was added to the gibson and the entire volume added to the PCR tube
Protocol:
●
Colony PCR Protocol
Ran Gel
No insert bands appeared
Suspected that the yib and pSMART labels were switched as the control was a pSMART and not the intended yib; labeling has been changed on tubes and on the picture.
Thursday, 5/26/16
Econo Taq PCR (Ben)
Goal: Test YibDp and pSmart in freezer to see if they are mislabeled; Is there a better Master Mix Recipe?
Protocol:
●
Colony PCR Protocol
Two Master Mixes were made
●
MM1 used the protocol given us by Charlie (0.25uL of each primer).
●
MM2 used the protocol Adam remembers (1.25uL of each primer in each tube).
The YibDp and the pSmart in the freezer were run on the PCR machine under each of these MM conditions. The mixes are given below:
●
Added 25uL EconoTaq / .5uL SL1 / .5uL SR2 / 24uL pH2O to Master Mix 1. 23uL of this was added to two tubes. 1.5uL DNA added after.
○
Each Reaction: 12.5uL EconoTaq / .25uL each primer / 12uL pH2O / Total = 25uL - 2uL to account for potential pipetting error
●
Added 25uL EconoTaq / 2.5uL SL1 / 2.5uL SR2 / 20uL pH2O to Master Mix 2. 23uL of this was added to two tubes. 1.5uL DNA added after.
○
Each Reaction: 12.5uL EconoTaq / 1.25uL each primer / 10uL pH2O / Total = 25uL - 2uL to account for potential pipetting error.
●
These were run on the same PCR protocol as yesterday. (98C for 5min, then cycle x35: (98C for 30s) / (50C for 30s) / (72C for 3min)
Note: 3min is overkill… Whoops; specifically, the increased extension time is unnecessary due to our insert being ~1kb
The PCR was then ran on a gel
Expectation:
○
1kb band in both yibDp-GFPs, garbage in pSmart (since there is no insert)
○
If the results of the samples seem flipped, then the minipreps of the samples located in the fridge have their labels swapped
○
If the samples with 1.25 μL of primer are clearer, then the PCR protocol will be updated with this improvement
The bands indicate that the minipreps had their labels swapped.
PCR machine is proven effective at doing PCR.
0.25 uL of primer is adequate for good PCR results.

Mini Prep Protocol
Introduction
sdfghjkl;
Materials
- Mini Prep Kit
- Spin Columns
- Neutralize (B3) Buffer - 4 C fridge
- Epi Tubes
Procedure
- Before Beginning
- All centrifugation steps should be carried out at 13,000 RPM
- Add 4 volumes of ethanol (>= 95%) to one volume of Plasmid Wash Buffer 2.
- If precipitate has formed in Lysis Buffer (B2), incubate at 30-37 degrees C, inverting periodically to dissolve.
- Store Plasmid Neutralization Buffer (B3) at 4 degrees C.
- Miniprep
- Pellet 1-5 ml bacterial culture by centrifugation for 8 minutes at 3500 rpm. Discard supernatant.
- Resuspend pellet in 200 ul Plasmid Resuspension Buffer (B1 - pink). Vortex or pipet to ensure cells are completely resuspended. There should be no visible clumps.
- Add 200 ul Plasmid Lysis Buffer (B2 - blue).
- Gently invert tube 5-6 times.
- Incubate at room temperature for 1 minute.
- Color should change to dark pink, and solution will become transparent and viscous. Do not vortex.
- Add 400 ul of of Plasmid Neutralization Buffer (B3 - yellow).
- Gently invert tube until neutralized.
- Incubate at room temperature for 2 minutes.
- Sample is neutralized when color is uniformly yellow and precipitate forms. Do not vortex.
- Centrifuge lysate for 2-5 minutes.
- Carefully transfer supernatant to the spin column.
- Centrifuge for 1 minute. Discard flow-through.
- Re-insert column in the collection tube and add 200 uL of Plasmid Wash Buffer 1.
- Centrifuge for 1 minute. Discarding the flow-through is optional.
- Add 400 uL of Plasmid Wash Buffer 2 and centrifuge for 1 minute.
- Transfer column to a clean 1.5 mL microfuge tube. Use care to ensure that the tip of the column does not come into contact with the flow-through. If there is any doubt, re-spin the column for 1 minute.
- When centrifuging with the epi tubes, cross the lids together to prevent them from breaking off. If there is an odd number then the last one should stick out sideways. Don't place the lids up or down as they can break off during centrifugation.
- CRITICALAdd >= 30 uL DNA Elution Buffer to the center of the matrix. Wait for 1 minutes.
- Spin for 1 minute to elute DNA.
- Usually add 50 uL of Elution Buffer
- Nuclease-free water (pH 7-8.5) can also be used to elute the DNA
- Yield may slightly increase if a larger volume of DNA Elution Buffer is used. But the DNA will be less concentrated. For larger size DNA, (>= 10 kb) heating the elution buffer to 50 degrees C to use can improve yield.

Table1
- CRITICALCOPY AND PASTE TABLE, INSERT NUMBER OF REACTIONS DESIRED AND TABLE WILL AUTO CALC VALUES
- Aliquot out master mix + oligos into a sufficient number of PCR tubes to test colonies
- If your backbone + insert plates have many more colonies than your backbone only or insert only, you will need to test fewer colonies than if you have lots of colonies on your control plates
- Also include a control reaction with parent plasmid only
- Aliquot out some LB (+ antibiotic) into another set of tubes,one for each colony you are testing
- Pick a colony from your transformation plate with a sterile pipette tip
- Dab the colony into the PCR tube with the econotaq master mix
- Dab it again in the tube with LB
- Run the PCR according to manufacturer’s protocol, but with a long (5 min) initial melting step at 95-98
- NOTE: If you are including miniprepped DNA in the PCR reaction, dilute to 50 ng/uL.
- Thermocycler Protocol
- Start: 98C for 10 min.
- Cycle (x35)
- Melt 98C for 45s
- Anneal 50C for 45s
- Extend 72C for ___
- Time = (1 min / kbase)*length(longest amplificant)
- 4C for inf
- NOTE: When dealing with DNA samples instead of colony samples. Use 3 uL of 1ng/uL DNA
- If DNA sample is poor, use at most 50 ng/uL concentration
