GFP EXPRESSION ASSAY

Day 1: OVERNIGHTS

  • Prepare a 96 deep well plate with 1ml of TB + antibiotic
  • Inoculate well by taking at scraping from glycerol stock
  • Shake at 37deg 16-24hrs

Day 2: EXPRESSION

  • Prepare 96 deep well plate with 1ml of TB + antibiotic,
  • Inoculate well by taking 20ul of the overnight and place it in 1ml TB, do all inducible twice so to allow for induced verse uninducible expression
  • Grow on shaker at 37C for 1 hour
  • Induce all inducible constructs with 50ml of 10mM IPTG
  • Allow to grow for 18 hour at room temperature on a shaker

Day 3: DATA

  • Take overnights plates and spin on plate centrifuge for 20 minutes at 4000rpm
  • Pour of broth and resuspend in 1ml PBS 7.5 pH on plate shaker
  • Spin down PBS suspension for 20 minutes at 4000rpm
  • Pour of supernatant
  • Resuspend in 1ml PBS 7.5 pH on plate shaker
  • Take 100ul of PBS suspension and place into clear bottom plate reader plate
  • Take 100ul of PBS suspension and place into black plate reader plate
  • Read plates at 525nm and record data
