2009.9.3
PCR T3polymerase PCR a gradient 58, 60, 62, 65, 67



GEL Purification.

Enzyme Digestion

2009.9.4
Purify the product of enzyme digestion.

Ligation: pSB1K3 backbone T3 polymerase

Pick colonies of the T7p-CI  1-1M. PCR assessment: Shake each one of the correct colonies in the incubator.

2009.9.5
Miniprep 6 of the T3polymerase colonies. 5 of them are red. Enzyme Digestion assessment of the remaining one. At the same time PCR with the Sequencing primer for assessment.

Enzyme Digestion again to confirm: XhoI, NotI, (XbaI, SpeI), (XbaI, SpeI, HindIII) for assessment It is not a correct colony.

2009.9.6
PCR again the 3 counter plasmid. Same protocol. At the same time use the PCR product of last time to do nested PCR with Standard primer. No result for the nested PCR.

Again PCR 3 counter plasmid Purification; Enzyme Digestion one the PCR products with EcoRI and SpeI.

Ligation: T3 polymerase PCR product into pEASY-BLUNT. T3 polymerase PCR product after digestion into pSB1A2(ES).

Transformation.

Enzyme Digestion of the T7p-CI into 1-1M for Enzyme digestion assessment: Looks like no one is correct in size.

2009.9.8
Pick 10 colonies from the pEASY-BLUNT plate for assessment. Pick 5 colonies from the pSB1A2 plate.

Miniprep Enzyme Digestion with EcoRI and PstI None is correct!!!

2009.9.9
Enzyme Digestion of the 3 Counter plasmid with EcoRI and NheI, Gel purification of the correct insert that contains the T3 pol.

PCR using the purified insert as a template. PCR 2 tubes with Phusion, one without DMSO the other with DMSO.

Gel purification of the two bands.

PCR again using the Standard primer and product of the first cycle of PCR as template. GEL: It seems that the size is not correct. Purification and use some to confirm the size. It turns out that the size is actually correct.

The product is digested with by XbaI and PstI directly.

Ligation: T3 pol(XP) into pSB1A2

Transformation.

2009.9.11
Pick 10 colonies of the T3pol clone. No band Mniprep 5 plasmids. Digest with EcoRI and PstI for assessment It seems right for NO. 1,2,3,5.

Digest with: (ExoRI and PstI) (EcoRI and SpeI) (XbaI and PstI) (XbaI and SpeI) PCR with: Sequencing primer Standarlize primer Universal Primer

For assessment PCR Enzyme Digestion

All phenomenon shows that this time it is correct. Send for sequence, However, the forward primer has no signal, and the reverse primer shows more than one binding site. It is weird.

2009.9.15
Transformation from the part distribution the P2 activator PhiR73 delta and one of its promoter PO.

Plate overnight.

2009.9.16
Pick one of the PhiR73 delta colony and PO promoter colony, shake in the incubator.

Miniprep PhiR73 delta and PO promoter plasmid.

Use Phusion to PCR the PhiR73 delta plasmid over night.

The first PCR introduces one point mutation and the second introduces two.

2009.9.17
GEL of the PCR product

Purification of the GEL.

Blunting kination reaction 70 centigrade for 10min then 37 centigrade for 10min

Ligation.

Transformation: PointMutation1, PointMutation2.

Plate

2009.9.18
Pick from PointMutation1, PointMutation2 plate each 5 colonies. Shake in the incubator.

Miniprep the 11 tubes.

Enzyme Digestion: Digest PointMutation plasmids with EcoRI and PstI for assessment.

2009.9.19
Send pointmutation plasmid for sequencing.

2009.9.21
Enzyme Digestion PM9 with XbaI and PstI.

GEL. Purification.

Ligation: Sal promoter(sp) vector PM9(XP)

Transformation

2009.9.22
Pick colonies for PCR assessment. Get the correct colony.

Get Ara-SupD from GRC.

Enzyme Digestion with EcoRI SpeI.

Shake the Sal-PM9 colony in the incubator. Shake the pSB4K5 1-7G strain in the incubator.

Gel: get Ara-SupD (ES insert)

2009.9.23
Miniprep the two plasmids. Enzyme Digestion pSal-PM9 with XbaI and PstI Digest pSB4K5 with EcoRI and PstI Gel: get pSal-PM9 (XP insert), pSB4K5 EP backbone.

Ligation: pSal-PM9(XP insert) 3.5ul ara-supD(ES insert )3.5ul pSB4K5 EP vector 1ul ligase 1ul ligation buffer 1ul.

Ligation over night.

2009.9.24
Transformation.

2009.9.25
Pick colonies PCR assessment. No result. Maybe due to low copy plasmid.

Shake in the incubator.

2009.9.26
Miniprep.

Enzyme Digestion of the plasmids.

Gel assessment.

Get the correct colony.

2009.9.27
Second plasmid transformation: Shake the PO-GFP strain in the incubator to OD 0.4

Suspend with CaCl2 and make competent cells.

Transformation with the correct ara-supD-pSal-PM9 plasmid.

Plate over night.

2009.9.28
Shake the transformation from last night. Shake the ORgate-GFP strain.

Induction.
