Screening of the cloning of E0240 and FlhDC+promotor

Spreading the clones in order to obtain single colonies

Strain Resistance Ligation DNA cloned vector expected size of the fragment amplified by VF & VR mesured size
S159.1 kanamycine L139.1 E0240 (GFP tripart) pSB3K3 1192 bp 1,5 kb

S161.1 ampicilline L142.7 FlhDC+promotor pSB1A2 1403 bp 1,4

0,3 kb

The plates obtained from the speading of yesterday can't be used because there are not single colonies.
We have to try again, but with a stronger dilution of the bacteria or with a smaller volume of spreading.

  • Resuspension of some bacteria from the glycerol stock into 1 mL of LB+antibiotic
  • Dilution 10 and dilution 100
  • Spreading of each dilution on a LB plate containing the right antibiotic
  • Overnight incubation
