pT7 + RBS (3A Assembly) and  Ag43 + dT (standard assembly) ligation products were transformed and cultivated then some colonies were formed (12~16 colonies) so we confirmed really insert DNA (3A:pT7 and RBS, standard:Ag43 and dT) were inserted to vector or not by colony PCR.
 
-
;Colony PCR
 
-
Colony PCR for assembly products.Each product reacted recipes written below.
 
-
#picked up each 12(16 is best but there were only 12 colonies) colonies from LB plates by Autoclaved toothpicks.
 
-
#Dipped into 10ul DW in 1.5ml eppendorf tubes.
 
-
#from 10ul DW, 4ul was added in PCR reaction solution (below), 6ul was mixed with 200ul LB.
 
-
#Ran PCR machine in recipe below.
 
-
#Electrophoresis for confirmation of PCR results.

We couldn't confirm insert DNA were really ligated with Vector or not.
 
-
Next we tried confirmation of insert DNA by Electrophoresis of mini-prep products.
 
-
For mini-prep, we needed do liquid culture.
 
-
 
-
 
-
;Liquid culturing
 
-
Liquid culture for mini-prep((pT7 + RBS) on pSB1K3 and (Ag43 + dT) on pSB1AK3).
 
-
#Prepared 1800ul LB solutions.
 
-
#To these LB solutions, added 200ul of LB solutions (colony PCR solutions were pre-cultivated in about 2hrs) and each antibiotics(Km (for (pT7 + RBS) on pSB1K3) and Amp(for (Ag43 + dT) on pSB1AK3)).
 
-
#Cultivated 15hrs30min.

;Mini-prep
 
-
Mini-prep for some colonies (we selected colonies which showed more correct bands than other colonies, pT7+RBS were No.4, 5, 9, 10 colonies and Ag43 + dT were No.1, 2, 3, 4 colonies)cultivated in LBA(Ag43 + dT) and LBK(pT7 + RBS) in 15hrs 30min.
 
-
#Mini-prep for LB culturing products along the protocol of FastGene Plasmid Mini kit(Nippon Genetics).

#Electrophoresis (Used pre-migrated 1% agarose gels with 5ul EtBr)in 30min.

To confirm more about insert DNA, we tried to digest these DNA with EcoRI and PstI.
 
-
 
-
;Digestion
 
-
Digestion for confirmation of insert DNA. Each DNA mini-prep products were digested with E & P.
