-
Product:Ag43(K346007)=3120bp and 2070bp, pT7-RBS on pSB1K3=2247bp
 
-
We confirmed there are some kind of restriction enzyme site in K346007 (digested with SpeI, PstI) and pT7-RBS on pSB1K3 was successfully digested with EcoRI and PstI. Balance between d+(EcoRI) and d+(E&P:cut with EcoRI and PstI) is about 80bp.

dT(B0015) would be amplified incorrectly and couldn't get enough digestion product. So we tried another DNA amplification method: PCR then digested.

We migrated B0015 mini-prep psoduct, digestion product, and PCR product.
 
-
PCRed dT would have 429bp(100bp(added by forward primer) + 129bp(dT) + 200bp(added by reverse primer)). Most bright and thick band in this image has about 300~400 bp. We thought dT was amplified successfully.

===Liquid Culture===

Liquid culture for single colony isolated pT7-RBS on pSB1C3 and Ag43-dT on pSB1T3.

#Picked up one colony from single colony isolated plates by platinum loop.
 
-
#Dipped into 2ml of LBC and LBT.

===Mini-prep===
 
-
Mini-prep for liquid culture products cultivated from yesterday(16th).
 
-
We used FastGene Plasmid Mini Kit(Nippon Genetics) and got 50ul of DNA solutions.
 
-
 
-
===Electrophoresis===
 
-
Electrophoresis for digestion product of K346007(Ag43) with EcoRI and SpeI as a reference to confirm SpeI cuts correct site or not and PstI didn't work correctly(in past experiments). And mini-prep products of Ag43-dT on pSB1T3 and pT7-RBS on pSB1C3 also migrated.
 
-
 
-
 
-
If digestion were succeeded, there are two bands would be seen: about 3120bp and 2070bp.
 
-
And if mini-prep were succeeded, there would exist two bands in each lanes: about 5000bp and 2000bp.

-
 
-
In this result we confirmed Ag43 was successfully digested with EcoRI and SpeI, and there were no other extra bands which had been existed double digested with EcoRI & PstI and SpeI & PstI. '''would PstI not work correctly?'''
