Materials

  • Dual Luciferase Reporter Assay System (Promega # E1910)
  • Passive Lysis Buffer (PLB at 5X; Promega # E1941) at -20
  • Luciferase Assay Reagent (LARII ) at -70, use fresh aliquot, thaw at room temp and mix
  • Stop and Glo Reagent and Buffer at -20
  • Plate Reader (Book ahead for about 30 min total)


Protocol

  • Transfect cells with reporter and pRL vector (50:1) and plate in a 96 well white plate
  • Treat cells as required
  • Prepare 1X PLB using 5X stock and water
  • Wash wells once with 100 ul D-PBS -/-
  • Add 20 uL PLB to well and incubate on a shaker for 15 min at RT
  • Prepare Stop and Glo Reagent (dilute from 50X in Stop and Glo Buffer). Need 100 uL per assay. Reagent and LARII should be at room temperature
  • Set plate reader to luminesence
  • Ensure correct measurement head is installed (one light tube) and it is set to do a top read
  • Set temperature control to off
  • Set plate layout under protocol button for both Luciferase Assay I and Luciferase Assay II
  • Add 100 uL of LARII to lysates and read luminescence (2s delay, 10s measurement using Luciferase Assay I
  • Add 100 uL of Stop and Glo Reagent and read luminescence again using Luciferase Assay II
  • Calculate relative luciferase activity by dividing results from Assay I by Assay II
