Digestion:transformation of parts listed as below.

•lactose promoter(ampicilin)
•double terminator(ampicilin)
•4-17M:BBa_K325909(chloramphenicol)
•1-12M:BBa_E0240(ampicilin)
•2-17F:BBa_120260(kanamycin)

After transformation, we put E.coli in the plate which is containing the each antibiotic.

We failed to conduct transformation of 4-17M,1-12M,and2-17F ,but transformation of lactose promoter and double terminator worked out.

We could not work out transformation of 4-17M,1-12M,and2-17F. This was why we tried again.
However, these experiments were failed.

PCR amplification of SAM-P20 and ChiA

We performed colony direct PCRs from a S. albogriseolus colony and a S. avermitilis colony.

We prepared two kinds of templates:
  1. Picked a colony, suspended in 50ul of water and incubated 1min at 95 degree. Added 1ul to the reaction mixture.
  2. Picked a colony and dipped in the reaction mixture.
Gel electrophoresis indicated that the PCR amplifications were successful for a sample, ChiA, but it was a faint band. We decided to retry direct PCR of SAM-P20 and PCR of ChiA.

Saturday

Digestion(Mori)

Retry of PCR amplification of SAM-P20 and ChiA.

We amplified SAM-P20 by colony direct PCR and ChiA by PCR using the PCR product that performed yesterday.
Reaction mixture: The same components and volume as before.
PCR condition: The same PCR condition as before.
PCR for SAM-P20
We prepared two kinds of templates:
  1. Picked a colony, suspended in 50ul of TE buffer (pH8.0) and incubated 1min at 95 degrees. Added 5ul to the reaction mixture.
  2. Picked a colony and dipped in the reaction mixture.
PCR for ChiA
1μl of PCR product was added to the reaction mixture as template.
Gel electrophoresis indicated that the PCR amplifications were successful for all samples. However, an unexpected faint band, about 1000bp, was also observed in the sample of ChiA.


PCR purification of SAM-P20 and gel extraction of ChiA.

SAM-P20: 43.9 ng/μl
ChiA: 30.0 ng/μl

Restriction enzyme digestion

We performed restriction digestions for:
  1. SAM-P20 with EcoRI and SpeI
  2. ChiA with EcoRI and SpeI
Incubated overnight at 37 degrees.
