Analysis of the transformant of FlhDC+promotor

Analysis of the plasmids MP160.1 and MP160.2 (FlhDC+promotor in pSB1A2)
Control: MP143 (GFP generator in pSB1A2)

PCR

total volume reaction (25 µL)

12,5 µL Quick load PCR Mix 2X
0,5 µL O18
0,5 µL O19
1 µL DNA
10,5 µL water

Digestion

total volume reaction (30 µL)

2 µL DNA
3 µL buffer 2 10X
0,3 µL BSA 100X
1 µL XbaI
