SuperLight™ Luciferase Reporter Gene Assay Kit
- Bright bioluminescent reagent system for rapid quantitation of luciferase reporter gene expression in transfected cells and high-throughput drug screens.
- High sensitivity and wide detection range. Detection of as little of 2 fg luciferase and as few as 4 cells. Plus, the emitted light is linear over seven orders of magnitude.
- Compatible with routine laboratory and HTS formats. Assays can be performed in tubes or microplates, on LJL Analyst, Berthold Luminometer, Top-Count, MicroBeta counters, chemiluminescent image plate readers (CLIPR/LeadSeeker). Assay reagents compatible with all liquid handling systems.
- Fast and convenient. Homogeneous “mix-and-measure” assay allows detection of luciferase levels within 10 minutes. The optimally combined reagent system allows a single addition step, and simultaneous cell lysis and detection.
- Robust and amenable to HTS. Z factors of 0.6 to 0.8 are observed in 96-well and 384-well plates. Can be readily automated on HTS liquid handling systems.

- The SuperLight™ Luciferase Reporter Gene Assay is based on the quantitation of luciferase expression in mammalian, yeast or E. coil cells, using luciferin and ATP as substrates. The reaction results in light production which can be conveniently measured on a luminometer. This bioluminescent reporter gene assay is extremely sensitive and is especially suitable for quantifying luciferase expression in recombinant cells. This ultra-sensitive, homogeneous cell-based assay only requires adding a single reagent to the cells and measuring the light intensity after a short incubation step (2 minutes). Assays can be performed in tubes, cuvettes or multi-well plates. All kit components are compatible with culture media and with all liquid handling systems. With an extended luminescence emission kinetics (half-life 40 min), the SuperLight™ luciferase assays are especially suitable for high-throughput screening in 96-well, 384-well and 1536-well plates. In addition, the reagent provided in the kits has been formulated for maximum sensitivity, reproducibility and long shelf-life. Applications for this kit include gene regulation studies and high-throughput screening of gene modulator
Can we determine ATP concentration in E. coli cells?
Yes. Ishida A (2002, Anal. Biochem 305, 236-241) described using equal volumes of 10% TCA and E. coli cell culture. Let stand 3 min at room temp. Mix 1 vol of the cell extract with 19 vol of 25 mM Hepes, 17 mM NaOH, and adjust pH to 7.8.before assaying.
How to adapt your protocol for adherent cells when working in a 24-well format?
Lyse the cells in the 24 well plate, then add 50 µL cell lysate to 50 µL SuperLight Reagent (10 µL + 10 µL would work too). Alternatively, cells could be harvested with Trypsin/EDTA, resuspend cells in the same volume (200-500 µL of medium). Do the 50 µL + 50 μL assay.
