The gel shows that the results we not what we wanted due to there being two bands instead of 1 band showing the Pst1 site was not removed. (XX) Talked about light switch design LexA promoter instread of Gal promoter PhyB/PIF3 red light system
6/25/16
(XX) Miniprep mRPS12 TU and mRSP12 mls(total of 8 minipreps)6/27/16
(XX) Goal: Redo digest and harvest TU and mls Major steps: Cut mRPS12 TU with EcoRI/PstI Cut Mrps12 mls with EarI/SpeI Gel order: L,TU1a, TU1b, TU2a, TU2b, mls1a, mls1b, mls2a, mls2b Gel results: harvested TU bands from TU2a and TU2b (2 bands per tube) TU gel extract = 0.363 g harvested four mls bands (2 bands per tube) mls gel extract A = 0.342 g mls gel extract B = 0.255 g Other activities: QIA gel extraction kit Used nanodrop to test DNA amount: TU = 3.1 ng/μL mls A = 41.2 ng/μL mls B = 27.7 ng/μL *according to nanodrop readings, TU needs to be precipitate while we run NEBuilder on mls A and mls B (HC) Ran NEBuilder on P413 GPD and 16-1 fragment. 1μL DNA 3μL fragment 10μL NEBuilder HiFi DNA Assembly Master Mix 6μL Sterile DI water (JM/CH) The first thing we are doing is running the blunt end ligation protocol using NEB Quick Blunting Kit and the NEB Quick Ligation Kit This was done with 3 tubes of 416 CYC1 and 3 tubes of 426 GPD Next we did a transformation on one of the 416 CYC1 and one of the 426 GPD Those are spread on plates and are now incubating so we can use them tomorrow6/28/16
(JM/CH) Slow day today because all we can do is inoculate falcon tubes for 24 hours so we can run a mini-prep tomorrow We did 6 tubes of 416 CYC1 And 6 tubes of 426 GPD (XX) Goal: NEBuilder TU perform transformation for TU, mls A, and mls B Redo TU digest to check TU1a, TU2a: just PstI enzyme TU1b, TU2b: double digest (PstI/EcoRI) Redo NEBuilder mls A and mls B *due to programing issue?? Gel order: L, Uncut (TU), PstI TU1a, PstI/EcoRI TU1b, PstI TU2a, PstI/EcoRI TU2b Gel results: the band after only PstI cut seems too long – questioning the pSBIC3 mRPS12 TU stock??6/29/16
(JM/CH) After incubating for an undetermined amount of time due to our shaking incubators being complete pieces of shit we are now going to mini preps because we could not find the proper buffer for the boiling preps With the miniprep material we had we were able to do 3 tubes of 416 and 2 tubes of 426 Also made more LB Amp Ran the digest of the plasmids with Pst1-HF (XX) Transformation results: No transformants for mls Major steps: Check mls minipreps Cut with only EarI and run gel Other activities: Streak pRS416 (the vector with no promoter) on LB-Amp plates – for LexA light switch Transform competent E. Coli with pSBGPD416 A, plate on LB-Amp Gel order: L, mls A uncut, mls 1a cut Gel results: bad mls miniprep – questioning the mls stock??6/30/16
(JM/CH) Today we are running the gel of the digest that should result in seeing only one Pst1 site Gel Set-up Ladder / 416 1 / 416 2 / 416 3 / 426 1 / 426 2 Results: too blurry to come to any reasonable conclusion
Now to set up a proper gel to run tomorrow We need to set up two controls, which will be minipreps of the DNA plasmids with 2 Pst1 sites Also we will be using 5 of our blunt end ligated DNA (3 416, and 2 426) We will then also load two of the wells, one with 416 and one with 426, but uncut (XX) Found out that pSB416GPD I from last year has failed because it has an extra start codon before BB prefix Goal: extract mRPS12 TU from old pSB416 GPD I Major steps: Made a 20 digest – 10 to run gel and 10 to run NEBuilder 10 pSB416 GPD I from last year 1 EcoRI 1 PstI 2 CutSmart Buffer 7 sterile water Other activities: Streak pSBIC3mls I on LB-chloro Inoculate pSB416 GPD A in LB-Amp Inoculate pRS416 in LB-Amp Gel Results: Nice mRPS12 TU band on the gel, extract mRPS12 TU band Mass = 0.265 g Nanodrop results TU: 5.6 ng/μL *need to do precipitation

(HC) Ran a spin miniprep using the Monarch Nucleic Acid Purification Kit and the instructions inside on the P413 Transformant. Ran a digest 7μL of DNA 1μL of Cutsmart 1μL of PstI 1μL of Sterile water Ran gel with cut and uncut transformant Lane1: Ladder Lane 2: Cut Lane 3: Uncut
(JM/CH) Today we ran the gel that had out plasmids hopefully set for perfection ladder / 416 1 / 416 2 / 416 3 / 416 orig / 416 uncut / 426 uncut / 426 orig / 426 1 / 426 2 Results:
This shows that our gel yesterday is confirmed and every sample shows one band. The Pst1 worked due to the double bands in wells 5 and 8. Edit: After talk with PI the gel does not have correct size of bands. Still inconclusive. (XX) Precipitation of TU from yesterday resulted 3.8 ng/μL according to nanodrop. This result does not make sense and it might possibly due to nanodrop defecting DNA after gel isolation. So we continue on NEBuilder anyway. Other activities: miniprep pRS416 and pSB416 GPD A inoculate pSBIC3 mls in LB-chloro broth

7/19/16
(HC) Inoculated LB Amp tubes with colonies from plates
I selected two colonies from each plate and labeled them 1A, 1B, 2A, and 2B based on which plate and colony it was. (JM/CH) Today the plates have grown up nicely. We picked 3 colonies from each of the 2 plates (one 416 and one 426). Now they are growing up in the incubator. Creating lesson plan. (XX) Transformation from yesterday did not work because of the LB-Amp plates! **pSBIC3 is chloro selective!! Goal: Plate NEBuilder stuff from 7/8/16 on LB-chloro plates
7/20/16
(HC)Ran a miniprep on all 4 tubes that were inoculated with the cells from the P413 GPD plates, 3 minipreps for each tube for a total of 12 tubes. I used the Monarch Plasmid Miniprep Kit.

I cut out the bottom bands of Lanes 3, 5, 7, and 9 and kept them to eventually do a gel extraction. (JM/CH) Today we started off the day by doing mini preps to isolate our plasmids. Helped Holly with her 413 GPD miniprep. Worked on the 416CYC1 and 426 GPD miniprep Now we are going to do the blunt end ligation to cut out the extra Pst1 site in both the 416CYC1 and 426 GPD plasmids. The gel came back from the miniprep of 413 and can be seen above in Holly’s entry. Now we are finishing the blunt end ligation of the 416 and 426. We kept tubes of just the blunted DNA and we will have a stock of the ligated DNA as well. (XX) There are still no transformants for mls-yeGFP! L Goal: Miniprep TU transformants and diagnostic gel to check if we have any insert Redo mRPS12 mls double digest – start mls-yeGFP process from gel extraction Gel mass = 0.286 g Gel Order: L, A1, A2, A3, A4, B1, B2, Blank, mls uncut, mls cut (A1 to B2) are minipreps from TU transformants Gel Results: Gel shows TU transformants have no insert

(HC) Ran Spinpreps with QIAgen kit on cultures (XX) Goal: Miniprep culture using old QIAgene kit Regrow culture Digest and run a gel to test whether pSB416 GPD mls-yeGFP is successfully inserted? Major steps: Regrow culture: Add 4.5 mL LB-Amp broth into old culture Digest and gel: 5 DNA 1 EcoRI-HF 1 PstI-HF 1 CutSmart Buffer 2 sterile water Gel Order: L, 4A1, 4B1, 5B1, 6A1, 6B1, L Gel results: All minipreps worked and insert of mls-yeGFP into yeast vector pSB415 GPD was executed successfully! Other activities: Nanodrop pSB416 GPD mls-yeGFP minipreps: 4B1 = 410.4 ng/μL 4A1 = 283.1 ng/μL 5B1 = 175.7 ng/μL 6A1 = 413.4 ng/μL 6B1 = 168.2 ng/μL Pick 4B1, 5B1, 6B1 for yeast transformation DNA used: 4B1 = 2 5B1 = 3 6B1 = 3 Plate on CSM-URA: Spread 50 on plate Spread the rest of it on plate7/29/16
(HC) Ran a digest 5 μL of DNA from A1 1 μL of XbaI 1 μL of XhoI 1 μL of Cutsmart buffer 2 μL of Sterile Water Ran Gel extration from monach gel extraction kit Ran transformations with 2μL of DNA 1μL of Fragment 16-1 10μL of Builder Master Mix 7μL of Sterile Water (JM/CH) Today we ran a gel extraction so that our plasmid was the only DNA in the transformation step of our E. coli Mass of first tube: 0.990g Mass of second tube: 0.986g Mass of total 1: 1.225g Mass of total 2: 1.189g Mass of gel 1: 0.236g Mass of gel 2: 0.203g For gel extraction we followed the NEB protocol provided in the kit.7/30/16
(HC) Inoculate Cultures of LB-Amp7/31/16
(JM/CH) Today we came in and ran a transformation of our new plasmid into competent E. coli cells. We ran the protocol and then plated on LB Amp plates8/1/16
(HC)Ran Spinprep with QIAgen kit. Ran a digest with 2 μL of DNA 1 μL of PSTI 1 μL of Cutsmart buffer 6 μL of Sterile Water 2 μL of DNA 1 μL of XhoI 1 μL of Cutsmart buffer 6 μL of Sterile Water Ran gel Ladder / 1 uncut / 1PstI / 1 XhoI / 2 uncut / 2 PstI / 2 XhoI / P413-PstI site uncut / P413-PstI site PstI / P413-PstI site XhoI (JM) We came in today and the plates had not grown up enough so today in lab I decided to do grunt work which included autoclaving tips and micro centrifuge tubes. (XX)Made master plate with: Parent strain with pSB416 empty plasmid KO Mls-yeGFP8/2/16
(HC)Made Yeast competent cells. (JM/CH) Today our cells have grown enough in both of the plates 2-2 from tube 1 and tube 2. We picked 2 colonies from each plate to make 4 cultures that will now grow overnight. Looked into using chromophores to verify expression. Transformed the chromophore provided to us in the 2016 distribution kit (19E) into E. Coli and plated on LB Amp. to grow overnight8/3/16
(JM/CH) Yeah…… pSB1C3 is chloro resistant, not Amp. Re-plated the transformants onto LB Chloro plates and incubated overnight. Used the QIAgen kit to prepare spinpreps of the transformants and ran digests with 1 μL of DNA 1 μL of PstI 1 μL of Cutsmart buffer 7 μL of Sterile Water Uncut BE ligated products and one spinprep of 416CYC1 that was not BE ligated was cut with PstI were used as controls.
