  • Two flasks with 50 ml + 100 µl kanamycin were incoluated each with 1 ml of the pre-preculture of each construct (P980, P983, P985).

Expression of P980, P983 and P985

Investigator: Florian, Rosario

Aim of the experiment: Expression of P980, P983 and P985.

Procedure:

  • 4 ml 1:500 Kanamycin mix were added to each of six 2 l flasks of LB medium, then they were inoculated with 50 ml overnight cultures (two flask for each construct).
  • After the culture reached an OD of 0.7, expression was induced by adding 20 ml of 500 mM Arabinose solution to each flask. Protein expression was continued for 5 hours.
  • Then the cells were pelleted by centrifuging for 10 min at 5000 rpm.
  • The pellets were resuspended in 20 ml SA buffer containing 0.5 mg/ml Lysozyme.
  • After short incubation the cells were disrupted by the application of ultrasound.
  • The disrupted cells were centrifuged at 20000 rpm for 1 hour to remove cell pieces and aggregate.
  • The supernatant was put in dialysis tubes and suspended in SA buffer overnight.

Lane Digestion of P928 with EcoRI & NgoMIV 2-log DNA ladder Digestion of P1000 with XbaI & AgeI Digestion of P1002 with XbaI & PstI
Results as expected; band was cut out as expected; lower band was cut out as expected; upper band was cut out
  • Gel extraction was performed after preparative gelelectrophoresis with QIQquick Gel Extration Kit, QIAGEN.
  • The resulting fragments were named F308 for digested P928, F309 for digested P1000 and F310 for digested P1002.
