Ligation Procedure:Lumazine/LuxY with plasmid pSB1C3 and promoters J23101/J23102. I'm working in Step 7 of the Ligation Procedure: Lumazine/LuxY with plasmid pSB1C3 and promoters J23101/J23102. 7.Colony PCR to confirm ligations: Analyze the colonies with Colony PCR to confirm that they contain the correct ligation. The primers that I am using are: Forward (5'->3'): Preffix primer. Reverse:(5'->3'): Suffix primer. These primers would amplify Lumazine/LuxY ligated to each promoter, if the ligation was correctly done. Results:Ligations Lumazine/LuxY with plasmid pSB1C3 and promoters J23101/J23102.Procedure Step 7 After re-culturing the colonies transformed with each ligation mixture, only colonies harboring the Lumazine/LuxY Mr.gene constructions fused to J23101 and J23102 grew correctly. Colonies selected to do the colony PCR reactions: Lumazine + J23101 ligation from colonies 1,5 and 15. Lumazine + J23102 ligation from colony 1,6 and 12. LuxY + J23101 ligation from colony 1, 2 and 15. LuxY + J23102 ligation from colony 2,4 and 5. Colony PCRs Ligations Lumazine/LuxY+promoters J23101 and J23102..Lane1:Ladder.
