The Thermo Scientific Pierce Gaussia-Firefly Luciferase dual assay kit provides the necessary reagents to simultaneously detect intracellular Gaussia and red firefly luciferase activity in mammalian whole cell lysates.

• Simultaneous—concurrent, filter-based, wavelength-separated detection of two luciferase activities
• Sensitive—measure bright blue Gaussia and red firefly luciferase activities in the same sample
• Fast—no quenching step required, unlike in traditional sequential dual assays
• Multiplex—capable of quantitating two cellular activities in the same sample(s)

Gaussia luciferase acts as an experimental reporter with constitutively active red firefly as a normalisation control. The assay working solution contains substrates for both luciferases, and the reactions occur simultaneously with flash-type kinetics. The resulting luminescent signals are spectrally resolvable using filters. In a single sample, researchers can assay transcriptional activity of regulatory elements, signal transduction pathways, and effects of activators or inhibitors.
