Plan
Aim: Create yeast cells that express LDLR on their cell membrane
Methods:
- Clone the LDLR gene.
- Create biobrick of LDLR.
July
We got LDLR cDNA and tried cloning.
Both ends of LDLR contains a lot of GC,so we had hard time...
7/6
Overview:
1.PCR LDLR gene from plasmid containing LDLR cDNA
2.gel-purify DNA from the PCR product
3.insert the DNA to vector (iGEM parts)
4.Transform into E. coli and select for ampicillin resistance
5.check for Transformation success using colony PCR by LDLR primers
Constructs to be created:
pGal1-Kozak-LDLR-terminator
Obtaining DNA:
Resuspended DNA in the following wells with 10ul water:
plate 1 7D
pGal1(including Kozak sequence)
[http://partsregistry.org/wiki/index.php?title=Part:BBa_J63006 Gal1 promoter]
Transformed 1ul of each of the above into DH5a competent cells:
- Mix 1ul of DNA with 100ul of competent cells on ice.
- Leave on ice for 30 minutes.
- Heat shock at 42ºC for 45 seconds.
- Leave on ice for 2 minutes.
- Add 500ul of LB and incubate at 37ºC for 1 hour.
- Plate on LB-ampicillin plates.

5.go to 2. 29times
but,unsucessful.
7/27
Miniprep of E.coli cells containing LDLR gene(that yesterday picked up and cultured) with Promega, Wizard Plus SV Miniprep DNA Purification System
using AGE, found a colony that has LDLR infusion plasmid
7/30
- sequencing of LDLR
August
We found our plasmid that we got first didn't include LDLR cDNA!? We came back to start line again!?
8/1
PCR of GFP for fusion
program
1.95ºC 2min
2.95ºC 30sec
3.55ºC 30sec
4.72.5ºC 20sec
5.go to 2. 29 times
6.25ºC forever
We found that the length of these PCR product till now was longer than that of LDLR.
->the result didn't conform with NCBI datebase
- change PCR program→didn't get the PCR product whose length was correct
8/2
- Sequencing of LDLR
8/4
The following were sequenced using the labeled primers:
- 1)F-spe1-Gall p-LDLR-5
- 2)F-pst1-Gall p-LDLR-3
Results:
Sequence read failed
8/5
- Sequencing of LDLR

2.95ºC 30sec
3.52~55ºC 30sec
4.72.5ºC 60sec
5.go to 2. 29 times
6.25ºC forever

2.95ºC 30sec
3.57ºC 30sec
4.72.5ºC 60sec
5.go to 2. 29 times
6.25ºC forever
The change point of this program is the temperature at third step.
This temperature is 57ºC but previous is 52~55ºC.
result;
The length of LDLR is 2500~3000bp.
8/9
- PCR of LDLR
8/10
- Sequencing of LDLR
The following were sequenced using the labeled primers
1)1D-LDLR-5'
