July 18

Colonies 1-6 from Gibson plates; 7 and 8 are reswabs of two colonies. From left to right: DNA ladder,(PNT001; colony 1; vector), P2v, P3v, P4v, P5v, P6v, P7v, P8v, (PNT001; colony 1; insert), P3i, P4i, P5i, P6i

from left to right: DNA ladder, (PNT001; reswab 7; insert), P8i, (16s; colony A; vector), 16Bv, 16Cv, (16s; A; insert), 16Bi, 16Ci

Colony PCR of 16s plasmids, for vector and insert
Gel of short PCR parts to confirm they are being amplified
Pulsed field gel with a larger amount of soil sample DNA
Retransform pSB3K5 into Xl-10s

Results

Gels show mostly expected single bands

July 19

PCR parts for Gibson assembly of pNT001, pNT003 and Joe's positive GFP control

Results

pSB3K5 plate had 0 colonies.
PFGE of soil-extracted DNA shows a smear; will do gel extraction of ~40kbp sequences for fosmid kit.

Gibson PCR concentrations

July 20

Pulse field gel of soil-extracted DNA, in preparation for fosmid insertion
PCR parts for Gibson assembly of pNT001, pNT003 and positive control
Redo Gibson assembly of pNT001 using a smaller total mass of DNA. Gibson assemble GFP from Joe that is known to have worked before as a positive control
Try transforming pSB3K5 with less DNA and as a liquid culture

Gel extraction of 40kb LA River sample DNA from pulse field gel
Transform pSB3K3 into competent cells, since the pSB3K5 transform is not working
