Summary:

For régulation system:

  • 1.For those transformation products(of yesterday), RBS+LacS+terminator in PSB1C3 plasmid, the liquid culture has been performed for further experiments. The oligopetides for PCR amplification was made bioinformaticly. The transformation for the terminator BBa_B0010 was still fail.
  • 2. The plasmid which contains fnr+RBS+LacZ+terminator and fnr+RBS+AmilCP+terminator was extracted. The restiction digest was performeed for them.

For sensor system:

  • 3. The selection of bacterian colonies was achieved by analyzing PCR product. The baterian selected are BphR1 c5 and c6; BphR2 c3 and c4; BphA1 c5 and c6,c7,c8.

Lab work

A.aero/anaerobic regulation system:

  • BioBrick RBS+LacZ+terminator in plasmid PSB1C3

Transformation for BBa_I732019 terminator

After ong night culture, we observed 2 tiny colonies on the medium. We continued the experiments by performing another liquid culture at 37°C with ampicillin.

Transformation for BBa_B0010 was always no go


Verification the transformation of BBa_I004450 in PSB3K3 by digestion and eletrophoresis

We performed 2 types of digestion:

Simple digestion:

  • DNA: 3µl
  • Buffe:r 3 µl
  • Enzyme: 1µl
  • H2O: 23µl
  • Total: 30µl

Double digestion:

  • DNA: 5µl
  • Buffer: 3 µl
  • Enzyme: 2µl
  • H2O: 20µl
  • Total: 30µl

Buffer used:

  • Ecor I+ PST I -> orange
  • Xho I -> green
  • Sac II -> blue
  • XhoI+Sac II -> green

After the digestion, we performed a eletrophoresis for verification:

PSPCR110713d.jpg
  • Well 1,7 :XhoI+Sac II
  • Well 2,8 :Sac II
  • Well 3,9 :Ecor I+ PST I
  • Well 4,10 :Xho I
  • Well 5,11 : control no digested
  • gel 0.8%


Estimed size and observed size:

enzyme estimed size observed size
Ecor I+PST I 1069bp and 2750 bp 1000bp and 2700bp
Xho I 2976bp+842bp 4000bp
Sac II 3819bp 4000bp
Xho I+Sac II 843bp,616bp,2367bp 1200bp and 2000bp

We confimed the existence of BBa_I04550 in plasmid PSB3K3.


B.PCBs sensor system:

  • Construction for BioBrick promoter promoter BphR1, BphR2, BphA1


Colony PCR

From the culture of cloning for promoter BphR1, BphR2, BphA1 which we seeded yesterday, we had chosen 8 colonies in total for further test. And like we did for promoter fnr, we used 8 primers for PCR amplification, they were: BphR1 up/down, BphR2 up/down, BphA1 up/down and Vf/VR.

In order to make clear this large number of PCR tubes, we classified them into 4 lots. they were:
Mix A : promoter BphR1

  • buffer go ta:(1X) : 5µl
  • MgCL2: 2µl
  • dNTP: 1µl
  • primers(R1_up/VR or VF/R1_down): 0.125µl
  • DNA: 2µl
  • Enzyme: 0.25µl
  • H2O: about 14.5µl
  • total: 25µl

Mix B : promoter BphR2
  • buffer go ta:(1X) : 5µl
  • MgCL2: 2µl
  • dNTP: 1µl
  • primers(R2_up/VR or VF/R2_down): 0.125µl
  • DNA: 2µl
  • Enzyme: 0.25µl
  • H2O: about 14.5µl
  • total: 25µl

Mix C : promoter BphA1
  • buffer go ta:(1X) : 5µl
  • MgCL2: 2µl
  • dNTP: 1µl
  • primers(A1_up/VR or VF/A1_down): 0.125µl
  • DNA: 2µl
  • Enzyme: 0.25µl
  • H2O: about 14.5µl
  • total: 25µl

Mix D :
  • buffer go ta:(1X) : 5µl
  • MgCL2: 2µl
  • dNTP: 1µl
  • primers(VF/VR): 0.125µL
  • DNA: 2µl
  • Enzyme: 0.25µl
  • H2O: about 14.5µl
  • total: 25µl

Result : can not find images <p>We considered that promoter BphR1 clone 5 and 6, promoter BphR2 clone 3 and 4, promoter BphA1 clone 5 to 8 accords our estimation. We got them in stock.
