Colony of PCR of S-E840

To check that S GFP is correctly inserted, we did colony PCR.

Gel: Agarose Time: 35min Voltage: 100V Maker: 1K 100 1～6 S-GFP① 7～13 S-GFP② Posi E840（about 900bp） Nega None

As a result, 1,3,5,6,11,12,13 are inserted S gene correctly. So, we decided to use 6 as S-E840①　and 11 as S-E840②.

ML2
MS

ML1 and ML2

pSB4K5 is inserted RFP generator. We didn't distinguish this inserted parts from low copy plasmid backbone, so self-ligated colony is red. So, white colony is correctly inserted parts. However, white colonies and green colonies are observed in ML1 and ML2 plate. We cultured both white and green colonies.

MS Self-ligated colony is red Many of colonies are red, however, green colonies are observed.

As a result, deletion is succeeded, however, point mutation is failed. It is because DpnI is too little to digest all of template DNA.

Making culture and Master plate

lacP rrΔTMD1GFP	Many colonies
lacP rrΔTMD1GFP(control)	Some colonies
constP rrΔTMD1GFP	Many colonies
constP rrΔTMD1GFP(control)	Many colonies
lacP rSRRz low	No colony
lacP rSRRz low(control)	No colony

Discussion: There ware some colonies, which emitted green light, on the plate 1. So, we cultured those colonies on master plate. On the plate 5 and 6, even though we used KRX, which is able to repress lac promoter, colonies might be dead. However, we still have to do some experience so that we confirm lac promoter cannot repress enough and E. coli cannot survive.

45min

Discussion: There were two band at the bottom of the gel. It was too long -45min-, and insert and vector might be contaminated. But we went on next operation.

Discussion: From sample 1, two vectors might be ligated. Sample 3 and 4, rSRRz might be inserted in low copy plasmid correctly. Sample 11, it might be the self-ligation product of low copy plasmid. Anyway, we decided to culture those 4 colonies on master plate.
