Team:Caltech/Week 8

July 31

Started a LB+amp overnight culture of the B0034 glycerol stock from the 2010 Caltech iGEM Team

Results

Mass spectrometry did not run correctly; samples did not ionize; must rerun

August 1

PCR pSB3K3 and pNT003 insert with the new primers.
Gel extract the pNT002 insert from the July 29 PCR
Standard Assembly Digest: K123001, B0014, B0034, R0010, pSB4A5
Minimal media transfers
Transformation and plating of pUC19 into competent cells for cell dry weight experiment
Overnight culture of B0034 glycerol stock
Overnight ligation of pNT002 insert and PSB3K3 backbone
Restriction digest of parts for pNT002 standard assembly and overnight ligation

Results

No colonies visible on the pUC19-transformed cells

The enrichment culture plates show no visible growth yet.

Gel showed that the terminator, RBS, and lac promoter did not digest for standard assembly.
Gel Extractions of July 29 PCR of pNT002 and pNT003 inserts

August 2

Gibson assemble pNT002 using the gel extracted insert and linearized pSB3K3
Gibson assemble pNT003 using the gel extracted insert and linearized pSB4A5
Transform Gibson reactions into our XL-10 cells and Emzo's top ten cells
Replating of more pUC19-transformed competent cells and non-transformed competent cells
Standard Assembly Digest- K12300, B1004, R0010, B0034, along with the destination plasmids.
Run gel of overnight pNT002 ligations
Transformed pNT002 insert+ pSB3K3 ligation

Results

lane 1 NEB 2-log ladder, 2-4 pNT003 insert, 5-7 pNT003 insert with PIPE primers, 8-13 pSB3K3, 14-15 pETDEST53

lane 1 NEB 2-log ladder, 2-4 pNT003 insert, 5-7 pNT003 inset with PIPE primers, 8-9 pNT003 insert, 10-11 pNT003 inset with PIPE primers, 12-15 pETDEST53

pNT002 ligation showed band on gel

August 3

Colony PCR of Gibson transforms
Another assembly digest with gel extraction.
Emzo's protocol for traditional assembly of PCR'd pNT002 insert and pSB3K3 plasmid

Results

Only the enzyme and the vector had correct band lengths on the gel. We extracted them and nanodropped, but concentrations too low.

August 4

Ran gel of colony pcr from yesterday
Ran two separate gels for standard assembly according to the number of base pairs each had.
The first 1.3% agarose gel had a 100 bp ladder with R0010 (200 bp), B0014 (95 bp), and B0034 (12 bp).
The second 1% agarose gel had a 2-log ladder with K123001 (1284 bp) and pSB4A5 (3395 bp).
Grow two overnight cultures of 175mL LB-chlor in preparation of dry cell experiment

Results

Some of the colony PCR have insert amplifications of the correct length. Will send some off for sequencing tomorrow.

upper comb lane 1 NEB 2-log ladder, 2-14 pNT002 colonies 1-13 vector amplification; lower comb 1 NEB 2-log ladder, 2-14 pNT002 colonies 1-13 insert amplification

lane 1 NEB 2-log ladder, 2-8 pNT002 colonies 14-20 vector amplification, 9-15 pNT002 colonies 14-20 insert amplifications

upper comb lane 1 NEB 2-log ladder, 2-13 pNT003 colonies 1-12 vector amplification; lower comb 1 NEB 2-log ladder, 2-13 pNT003 colonies 1-12 insert amplification

No growth from traditional assembly on self ligation control or experimental plate
Blue light showed bands for all the parts, but again the smaller parts had the wrong band lengths.

August 5

Miniprepped colonies from Gibson colony pcr (pNT003-2,8,11,12 and pNT002-6,11,12,14)
Sent pNT002-14 and pNT003-2,8,11,12 off for sequencing as the others were too dilute
PCR 16s sequences
Rerun p450 degradation assay for GCMS analysis
Begin growing biofilms in 96-well plate and Erlenmeyer flasks with pipette tips, glass beads, and wood chips with different OD's of XL-10 Assembled DDT gene and transformed into XL-10s

Results

The gel for 16s had no bands in any of the control or sample lanes.

The transformations for the DDT gene yielded no colonies. Will redo assembly.

August 6

Transfer 96-well plate and flasks to 37°C incubator
