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

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.

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.
