Electrophoresis

We confirmed success of digestion by electrophoresis.
The DNA was extracted from TBE gel and we got DNA solution.

Gel extraction

The digestion product was extracted. Used FastGene Gel&PCR extraction kit(NipponGenetics)and got 50 ul of DNA solution.

Digestion

Digestion to divide PhaA and PhaB with XbaI and PstI.
I digested PhaC(BBa_K342001) with these restriction sites and also XhoI to divide pSB1C3 into pieces, on which PhaC is, that is because the length of pSB1C3 is nearly PhaC.
And we digested PhaC (BBa_K342001) and pSB1C3 by XbaI and SpeI.

PHB polymer ethanolysis

We did ethanolysisãof PHB polymer for 4 hrs with sample 2~8.

Preparation for GC/MS

We did the preparation for GC/MS with sample 2~8.

PCR

We multiplied pSB1C3 by PCR. Used two different DNA polymerase, KOD-Plus-Neo and KAPA Taq.

August 30th

Ethanol precipitation

Diegested phaA by XbaI and SpeI and RBS by SpeI were condensed by Ethanol precipitation.

Ligation

PhaA and RBS, PhaB and RBS, PhaB and pSB1C3 were ligated each other.
And the DNA were transformed into bacteria.

Colony PCR

The length of PhaB on pSB1C3 was confirmed by colony PCR.
The result showed PhaB and pSB1C3 didn't ligate correctly.

Liquid Culture

Incubation of bacteria holds RBS (BBa_B0034) - PhaC (K342001) was started.

August 31st

Colony PCR

We confirmed the length of the three constructs that transformed at August 30th.
The result showed RBS and PhaA were ligated correctly.
So the incubation was started.

Plasmid extraction

Plasmid of RBS-PhaC were extracted.
And then we got 50ul DNA solution.

Liquid culture

Incubation of bacteria holds dT (BBa_B0015) was started.

September 1st

Plasmid extraction

Plasmids of RBS-PhaA and dT (BBa_B0015) were extracted.
And then we got 50ul DNA solution.

Fig. Extracted plasmids of dT and RBS-PhaA on pSB1A2

1: dT on pSB1AK3 (About 3.3kbp)
2 to 4: RBS-PhaA on pSB1A2 (About 3.2kbp)
5 to 7: RBS-PhaC on pSB1A2 (About 4.1kbp)
We thought sample 4 is not ideal plasmid and trashed it.

Digestion

RBS-PhaA was digested by XbaI and SpeI restriction site to ligate with RBS-PhaC digested by SpeI site. HokkaidoU 120901 RBS-PhaA RBS-PhaC digestion.jpg

  • 1 and 2 is digested RBS-PhaA on pSB1A2.
  • Upper fragment is vector, pSB1A2.
  • Lower one is an objective fragment, RBS-PhaA (About 1.2kbp).
  • And PhaB and pSB1C3 were digested with XbaI and SpeI site.
    We decided to try ligation PhaB with pSB1C3 again.

Electrophoresis

We confirmed success of digestion by electrophoresis.
The DNA was extracted from TBE gel and we got DNA solution.

September 2nd

Ethanol precipitation

The digested DNAs, RBS-PhaA (No. 1), RBS-PhaA (No. 2), RBS-PhaC on pSB1A2, PhaB and pSB1C3 were concentrated by Ethanol precipitation.

Ligation

RBS-PhaA (No. 1 and No. 2) was ligated with RBS-PhaC on pSB1A2.
And PhaB was taken in pSB1C3.

Transformation

These ligated DNAs transformed into E. coli (strain: DH5α).
And then we spread fungus liquid added LB on LB plates include antibiotics.
