Gel 1 of 2. Lane 1: ladder; lanes 2-4: PCR product using VF2 and VR of plasmid containing esp ligated with rsaA C-terminal that had been digested 20110606; lane 5: PCR product of plasmid containing esp; lanes 6-8: PCR product using VF2 and VR of plasmid containing esp ligated with rsaA C-terminal PCR product from 20110605. Only lane 6 shows successful ligation of esp and rsaA C-terminal.

Gel of PCR of Caulobacter promoters Pxyl (inducible) and PrsaA (constitutive). Lane 1: ladder; lane 2: PrsaA; Lane 3: Pxyl. Bands appear, but are hazy and spread out due to the small size of DNA fragments.
|
PCR products of Caulobacter promoters PrsaA and Pxyl. Lane 1: ladder; lane 2: PrsaA; lane 3: Pxyl.

Gel confirming that clean up did not remove DNA fragments. Lane 1: ladder; lane 2: PrsaA; lane 3: Pxyl.
|
Gel of PCR products of transformations of insertion of Biobrick promoter BBa_K081005 into pSB1C3 containing esp and rsaA C-terminal. Lane 1: ladder; lanes 2-4 and 6-8: PCR product of transformation survivors; lane 5: control DNA of esp + rsaA C-terminal. Only lane 2 shows something that may be success, but as the fragment for the promoter is so small, it is difficult to confirm based solely on gel electrophoresis.
|

|
Gel of BBa_K081005 digests from minipreps. Lane 1: ladder; lane 2: digest of miniprep from overnights that should carry the desired promoter insert. Digest shows one band: the linearized plasmid.
|
Lanes 1-6: plasmid PCR of transformed cells that should carry the desired esp insert; lane 7: ladder; lanes 8-10: plasmid PCR of transformed cells that should be carrying esp + rsaA C-terminal insert. A few of the esp inserts succeeded, but as expected the three piece ligation failed again.
|

|
Gel 2 of 2. Colony PCR of transformation products of insertions of esp from PCR into pSB1C3 containing rsaA C-terminal, insertions of rsaA C-terminal into pSB1C3 containing esp, and esp and rsaA C-terminal digests from pSB1C3 into pMR10 as a three piece ligation.

Colony PCR products of transformation products of insertions of esp + rsaA C-terminal into plasmid containing Caulobacter constitutive promoter PrsaA. Lane 1: ladder; lanes 2-7: PCR products; lane 8: standard PCR product of pSB1C3 containing only PrsaA. Transformation was successful, but ligation, and perhaps digestion, were not.
|
Colony PCR products of transformation products of insertion of esp + rsaA into pSB1C3 containing Caulobacter inducible promoter Pxyl (induced in presence of xylene). Lane 1: ladder; lanes 2-7: PCR products; lane 8: standard PCR product of pSB1C3 containing only Pxyl. Transformation was successful, but ligation was not.

Lane 1: ladder; lanes 2-7: PCR products; lane 8: standard DNA fragment identified as containing BBa_K081005. The lack of DNA may be due to a breakdown in our antibiotic; the transformation is being repeated.

Gel 1 of 2. PCR products of transformation cells that should contain esp + rsaA C-terminal insert into plasmids containing various promoters. Lane 1: ladder; lanes 2-5: inserts into plasmid containing BBa_K081005; lane 6: standard BBa_K081005 containing no insert; lanes 7-10: inserts into plasmid containing Pxyl. While the BBa_K081005 plasmids seem to have some insert, none of these show an insert of appropriate size (~1.3-1.5kb).
|
Gel 2 of 2. PCR products of transformation cells that should contain esp + rsaA C-terminal insert into plasmids containing various promoters. Lane 1: ladder; lanes 2-7: inserts into plasmid containing PrsaA; lane 8: standard PrsaA with no insert; lane 9: standard Pxyl with no insert. The first lane shows odd results, but none of these seems to have the desired insert.
|
Test to ensure all of our restriction enzymes are still active.

There is an apparent decrease in size from standard DNA fragments to the digested samples. In the digest lanes there is also a dim band fairly far down the gel corresponding to the small end piece that is the other product of digestion.
|

Gel 1 of 3. PCR of transformation cells that should contain an insert of Pxyl into pSB1C3 containing esp and rsaA C-terminal. Lane 1: ladder; lanes 2-5: PCR with plasmid primers VF2 and VR; lanes 6-9: PCR with promoter specific forward primer and plasmid reverse primer VR. The lack of DNA is disturbing and suggests that our plates are ineffective or contaminated.
|
Gel 2 of 3. PCR of transformation cells that should contain an insert of PrsaA into pSB1C3 containing esp and rsaA C-terminal. Lane 1: ladder; lanes 2-5: PCR with plasmid primers VF2 and VR; lanes 6-9: PCR with promoter specific forward primer and plasmid reverse primer VR. Bands in lanes 2, 3, and 4 suggests that these colonies at least contained the plasmid, but the apparent size of the band is too small for esp and rsaA C-terminal together; rather it is the correct size for just rsaA C-terminal.
|
Gel 3 of 3. PCR product of transformation colonies that should contain an insert of either Pxyl or PrsaA into pSB1C3 containing esp and rsaA C-terminal. Lane 1: ladder; lanes 2,3: Pxyl insert PCR using plasmid primers VF2 and VR; lanes 4,5: PrsaA insert PCR using plasmid primers VF2 and VR; lanes 6,7: Pxyl insert PCR using promoter specific forward primer and VR; lanes 8,9: PrsaA insert PCR using promoter specific forward primer and VR. Lanes 8 and 9 suggest a successful insertion of PrsaA, however all of the bands are too small.
|
Verification of presence of lack of rsaA C-terminal insert in pSB1C3 containing esp. Lane 1: ladder; lane 2: digested PCR of possible insert; lane 3: standard digested esp. The band is faint, but there appears to be a band at the same height as the standard as well as a couple higher bands for leftover plasmids, suggesting that there was no insertion of rsaA C-terminal.

|
Gel 1 of 2. PCR of transformation products of rsaA C-terminal insert into pSB1C3 containing esp. Lane 1: ladder; lanes 2-7: ligation 1, colonies 1-6; lanes 8-10: ligation 2, colonies 1-3. The complete lack of DNA fragments here means that these ligations failed.
|
Gel 2 of 2. PCR of transformation products of rsaA C-terminal insert into pSB1C3 containing esp. Lane 1: ladder; lanes 2-4: ligation 2, colonies 4-6; lanes 5-10: ligation 3, colonies 1-6. All the bands here are correct for esp, but not the combination.

PCR test of transformation products of insertion of gel extracted DNA into plasmid containing another gene. Lane 1: ladder; lanes 2-4: insertion of rsaA C-terminal into plasmid containing esp; lanes 5-7: insertion of esp into plasmid containing rsaA C-terminal. Smearing of bands is inconclusive and suggests that there may be no DNA (colonies are contaminants) or that freeze-thaw did not succeed in providing sufficient template DNA for PCR.

Lane 2 shows that ligation was unsuccessful. The rest of the lanes are inconclusive and a follow up gel with additional DNA is to be run.
|
Lane 1: ladder; lane 2: ligation of esp and rsaA C-terminal fragments from gel extraction. No rsaA appears to be present, nor any ligation, only esp.
