2009.8.1

Transformation:
J23100-tetR-tetP and LuxR-LuxP-SupD

PCR assessment for the J23100-tetR- tetP and LuxR-LuxP-SupD
Overnight

2009.8.2

PCR product->GEL
PKU 20090802 Min Lin 1.JPG

Number2-6 J23100-tetR-tetP is correct.
Number1 of LuxR-LuxP-SupD is correct.

Digestion of the J23100-tetR-tetP
With EcoRI and SpeI overnight

2009.8.3

01:30
Help Zhangguosheng pick colonies and PCR

10:00
GEL

Enzyme Digest of the J23100-tetR-tetP with EcoRI and SpeI
PKU 20090803 Min Lin 4.JPG

GEL Purification.
Ligation:
J23100-tetR-tetP ES insert
E0840 EX vector and SupD-terminator EX vector

18:30
Transformation.

2009.8.4

PCR assessment
PKU 20090804 Min Lin 1.JPG

Shake the BL21 strain transformed with T7promoter-GFP by WangHao
Induce with IPTG.
The induced one has fluorescence

2009.8.5

Pick standard part I0500
Phusion PCR

PKU 20090805 Min Lin 1.JPG
GEL purification and then cut with EcoRI and SpeI.
Purify from digestion.

2009.8.6

Ligation of I0500(ES) to SupD-terminator and E0840 vector.

Transformation

In order to get a Kan resistant back bone, I transformed the pSB1K3 part from plate1-7A.

2009.8.7

Shake the 1-7A in the incubator.
PCR assessment of the I0500-GFP clone.
PKU 20090807 Min Lin 1.JPG
But it is no need to care about which is right, cause Gaorencheng has worked out a AraC and PBad promoter that works well.

2009.8.8

Miniprep the 1-7A plasmid.
Digest with EcoRI and PstI
PKU 20090808 Min Lin 1.JPG

GEL purification.
Store the backbone.

Ligation
T7promoter-GFP EP insert
pSB1K3 EP backbone

Transformation

2009.8.9

Pick colonies to do PCR assessment of the T7promoterpSB1K3
PKU 20090809 Min Lin 1.JPG
The 3 colonies are correct ones.

Induction of the LuxR-LuxP-GFP
A gradient of concentration:
5uM, 2uM, 100nM, 10nM, 1nM, 0
Use flocytometry to detect the fluorescence.
PKU 20090809 Min Lin 2.JPG
It shows a ten fold induction.
However the basal is very high.

Miniprep the LuxR-LuxP-SupD plasmid and the T7promoter- GFP-pSB1K3 plasmid.

2009.8.11

10:00
Help Zhangguosheng with his GEL

15:00
Enzyme Digestion of the LuxR-LuxP-T7ptag by XbaI and PstI

2009.8.13

Miniprep the Low copy plasmids, and digest with EcoRI and PstI.

Digest the LuxR-LuxP-SupD plasmid with SpeI and PstI, CIAP and then purify.
PKU 20090813 Min Lin 1.JPG

Ligation:
Insert: XP digestion of AraC-T7ptag insert (9x rbs)
Vector: LuxR-LuxP-SupD(SP)

2009.8.14

Shake the 3 counter plasmid in the incubator.
Miniprep the SupD-terminator plasmid. Digest with EcoRI and XbaI to make vectors.
PKU 20090814 Min Lin 1.JPG

Help Wushuke induce the pLac-RFP-JM109.
Miniprep the 3 counter plasmid.

2009.8.15

11:00
Phusion PCR of the 3 counter plasmid.
PKU 20090815 Min Lin 1.JPG
GEL purification.
Digest with EcoRI and PstI

Ligation:
pSB1K3 backbone 1 ul
T3 pol insert 7ul
