• Batch full of competent cells. OD: 0.495

• Ligation

LuxCD +LuxEG in pSB4K5 (L1) and pSB1K3 (L2).

• Gibson: sfGFP in pSB4K5. Assembly made to test new competent cells

• Transformation

Plates

L1: Ligated LuxCD +LuxEG in pSB4K5 at 1:1 and 1:10 L2: Ligated LuxCD +LuxEG in pSB1K3 at 1:1 and 1:10 G+: Gibson sfGFP in pSB4K5 PUC19 (AMP) x3: to test our new competent cells, 20µL of transformed bacteria were plated.

Tuesday

• Transformation results

PUC19-1: 148 colonies PUC19-2: 177 colonies PUC19-3: 155 colonies L1 and L2 with colonies. Colony PCR will be done. G+ Positive results. Several colonies. Probably due to: the problem with the Gibson assembly could be the use of E. cloni instead of TOP10.

• Colony PCR for LuxCDEG in pSB1K3: Negative. PCR will be tried.
• Colony PCR for LuxCDEG in pSB4K5 was not done due to all colonies that grew were red. It was assumed LUXCDEG did not integrate.
• PCR for RS1-Kan-B0015-RS2 (chloramphenicol resistance) and electrophoresis: primers form dimers. PCR will be repeated at higher Tm.

• PCR run:

Name PCR Template Primer F Primer R Length

1 RS1 KAN B0015 RS2 F8 F5 4300

2 KAN B0015 RS2 F8 F2 3760

Notes

• It was a touch-Down PCR

1 and 2 amplified and had right size. Only 1 will be purified because is more useful than 2.
