2009.9.4

Purify the product of enzyme digestion.

Ligation:
pSB1K3 backbone
T3 polymerase

Pick colonies of the T7p-CI  1-1M.
PCR assessment:
PKU 20090904 Min Lin 1.JPG
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.
PKU 20090905 Min Lin 1.JPG

Enzyme Digestion again to confirm:
XhoI, NotI, (XbaI, SpeI), (XbaI, SpeI, HindIII) for assessment
PKU 20090905 Min Lin 2.JPG
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.
PKU 20090906 Min Lin 1.JPG
No result for the nested PCR.

Again PCR 3 counter plasmid
PKU 20090906 Min Lin 2.JPG
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:
PKU 20090906 Min Lin 3.JPG
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
PKU 20090908 Min Lin 1.JPG
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.
PKU 20090909 Min Lin 1.JPG

Gel purification of the two bands.

PCR again using the Standard primer and product of the first cycle of PCR as template. GEL:
PKU 20090909 Min Lin 2.JPG
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.
PKU 20090909 Min Lin 3.JPG

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
PKU 20090911 Min Lin 1.JPG
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
PKU 20090911 Min Lin 3.JPG

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.
