July Week1: Plasmid Amplification

We chose pRSFDuet-1, pACYCDuet-1 and pCDFDuet-1 as expression vectors and pBluescript II KS(+) as the connector. These plasmids were amplified for further construction.

July Week2: Gene Construction

We intended to construct the gene of our fusion protein, ssDsbA-mRFP-HL-Lgt-FL-TAL-His tag, using overlap PCR, enzyme digestion and ligation. After careful consideration, we decided to connect ssDsbA-mRFP-HL-Lgt as one part of this fusion protein and FL-TAL-His tag for another, so that they could be connected together.

July Week3

Connected ssDsbA-FP-HL-lgt by splicing by overlap extension. Transform, colony picking plasmid extraction and digestion identification; Sequencing results showed accurate construction.

July Week4

Use golden gate to connected TAL of 2012 Freiburg igem. Transform, colony picking plasmid extraction and digestion identification.

August Week1-2

Test the conditions for the PCR. Connected TAL, transform, colony picking plasmid extraction and digestion identification. Find with our electrophoresis band. Expression vectors and connector plasmid are confirmed by sequencing.

August Week3

There are some problems about Freiburg’s parts. We can’t connected TAL in the right order. So we design some new primes for PCR that can produce the right sequence.

August Week4

Design a few new ports for the fusion protein. Sequencing results showed accurate construction. Observe the FP using LSCM to confirm the fusion protein can locate on the membrane.

September Week1

Try co-transformation: Prsf pacyc pBluescript . Find the conditions of protein expression. Find the way to construct the TAL.

September Week2

Find the enzymes for the application. Find the way to detect the substrate in these pathways. Connector plasmid modification.

September Week3

TAL gene synthesis. Construct the part with our new ports.

September Week4

TAL gene synthesis.
