Trojan Horse
ASDF18th September
Exp Silencing Kan
- Launch O/N culture of producing phages cells ; centrifuge ; take supernatant and filter it.
-diluting 100x O/N of MGZ1, F+ -pCola in LB-Kan (25 ug/ul)
- At OD 0,7 :. Put 900 uL of cells in each tube. Add in tubes respectively : nothing, 100uL phages of litmusGFP-LacZ1, litmusGFP-Kan1 & litmusGFP-Kan2
-2 replicates for each condition. Plate each Dilution 2 times to limit the variability
Non infected cells (1,2)
Cells infected with anti lacZ (1,2)
Cells infected with anti KanA (1,2)
Cells infected with anti KanB (1,2,)
- Incubate 70 minutes at 37°C
- Serial Dilute every tube until 10-5. Plate 100ul for each tube according to this dilution table
