PCR products on DNA gel. Lane 1: ladder; Lane 2: rsaA from liquid culture Caulobacter; Lane 3: rsaA from plate culture Caulobacter; Lane 4: esp from S. epidermidis.

Gel results for transformation of ligations. Lane 1: ladder; Lane 2: digested plasmid with rsaA C-terminal; Lane 3: digested plasmid with rsaA C-terminal and esp; Lanes 4-8: digested plasmids from various colonies with esp.

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 2 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. None of these show successful ligation.

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 PCR product of esp and rsaA C-terminal using new primers. Lane 1: ladder; lanes 2,3: PCR product of rsaA from chromosomal Caulobacter DNA; lane 4: PCR product of esp using new primers from chromosomal S. epidermidis DNA.

Gel of Plasmid PCR of promoters. Presence of two small bands shows contamination of samples. Lane 1: ladder; lanes 2-5: plasmid PCR of transformation survivors.

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.

Lanes 1-3 and 5-8: plasmid PCR of transformed cells that should carry the Promoter-esp-stop-rsaA insert in plasmid pMR10; lane 4: ladder. Only lane 3 shows any success.

Lanes 1-3 and 5-7: plasmid PCR of colonies that should be carrying rsaA C-terminal insert in pSB1C3; lane 4: ladder. Lanes 3 and 4 seem to show insert at significant concentrations.

Lane 1: ladder; lanes 2-4: plasmid PCR product of various promoter insertions into pSB1C3. Smearing due to leftover circular plasmid. Insertions seem to have been successful.

Gel 1 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. Lane 1: ladder; lanes 2-4: esp from PCR inserted into rsaA containing pSB1C3; lanes 5-7: rsaA from PCR inserted into esp containing pSB1C3; lanes 8-10: esp and rsaA digests from plasmid insertion into pMR10. Lanes 2-4 show correct insertion length, but none of the other fragments are the correct length.

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. Lane 1: ladder; lanes 2-4: esp from PCR inserted into rsaA containing pSB1C3; lanes 5-7: rsaA from PCR inserted into esp containing pSB1C3; lanes 8-10: esp and rsaA digests from plasmid insertion into pMR10. Lanes 2-4 show correct insertion length, but none of the other fragments are the correct length.

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.

Colony PCR amplified DNA fragments of transformation products of inserts into plasmid containing existing Biobrick promoter BBa_K081005. 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 P_xyl. 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 P_rsaA; lane 8: standard P_rsaA with no insert; lane 9: standard P_xyl with no insert. The first lane shows odd results, but none of these seems to have the desired insert.
