Team registration and brainstorm

During this time, we registrated the team SKLMT-China in iGEM. In order to verify the feasibility of our project, we discussed with professors and experts and did some human practice work.

week5

week7

In order to obtain an artificial promoter library suitable for cloning, promoter sequence flanked by homology arms was added a chloramphenicol selection marker. This sequence was synthesized by sangon ®.

TABLE 2 Oligonucleotides used for PCR of the DNA segment containing the promoter and chloramphenicol selective marker

Set up the PCR reaction using pR6K-cm-ccdB as a template. Typically, set up the PCR reaction (50ul in total) to obtain sufficient amounts of DNA.
Component Amount(ul) Final
Autoclaved ddH2O 22
2×primeSTAR max premix 25 1×
Template, 50ng ul-1 1 50 ng
Syn-promoter-1 Oligo(10uM) 1 30 pmol
promoter-2 Oligo(10uM) 1 30 pmol
Total 50

Carry out the PCR in a thermal cycle following the instructions below:

Cycle number Denaturation Annealing Termination
1 94℃,4min
2~31 98℃, 15s 59℃, 15s 72℃, 15s
32 72℃, 4min
33 10℃, hold
Purify the PCR products using the TianGen PCR Purification Kit and elute into 30ul of autoclaved ddH2O. Quantify the elution using a NanoDrop UV spectrophotometer

week8

transform the plasmid pBBR1-kan-amp-ccdb-BAD-GFP-firefly into GB05 red gyrA462 via electroporation. Do Mini-Prep and screen correct plasmid by restriction analysis

week9

construct the plasmid pBBR1-kan-cm-promoter(1-25)-firefly via liner circular recombination in GB05 red gyrA462. Do Mini-Prep and screen correct recombinants by restriction analysis.

week10

transform the plasmid pBBR1-kan-amp-ccdb-BAD-GFP-firefly into p.fluorescence pf-5 via electroporation.

week11

Chracterize the strength of different promoters by luciferase firefly assay.

Colleborate with seven Chinese iGEM teams to characterize the promoter strength under differdent conditions.
