Getting Promoter Plasmid and Iron Assay with Fur- Mutants

Promoter Plasmid

  • No colonies formed on the Kanamycin plates for I0500 and pUC control still
  • Re-selected promoter plasmid R0010 with ampicillin resistance in well 5E on plate 1002
  • Extracted R0010 from filter paper following standard protocol
  • Transform competent TOP10 with R0010 and J63006 again following standard transformation protocol with some amendments
  • R0010: 5μL DNA + 25μL TOP10 + 55μL SOC
  • J63006: 15μL DNA + 25μL TOP10 + 45μL SOC
  • Plate out neat and 1/10 dilution on freshly prepared ampicillin plates of 100μg/mL
  • Incubate overnight at 37°C
