The Thermo Scientific Pierce Firefly One-Step Luc Glow Assay Kit measures firefly luciferase activity in mammalian cell culture using a single reagent-addition step, making it ideal for high-throughput screening (HTS) applications.

Features of the Firefly One-Step Luc Glow Assay Kit:

Sensitive—highly sensitive detection of firefly luciferase activity
Odorless—reagents have no foul or toxic odor, eliminating the need to work in a fume hood
Convenient—one-step, mix-and-read protocol; no additional reagents required
Stable—increased signal half-life and stability compared to flash assays
Simple—does not require a luminometer with injectors
Automation-friendly—amenable to high throughput assays

This glow-type luciferase assay kit is designed for use with cultured mammalian cells that are transfected with vectors expressing the appropriate firefly luciferase reporter enzyme. Several features make the kit especially suitable for luminometers without injectors and for high-throughput screening (HTS) applications. The convenient, one-step, homogenous protocol minimizes handling steps to support the use of automation. Simply combine the supplied substrate solution and assay buffer to make a single working solution, and then add it to microplate wells containing the transfected, treated cells. The stable signal output (glow) of this system provides flexibility with regard to incubation time. When used with Thermo Scientific Firefly Luc Plasmids, the kit provides a highly sensitive bioluminescent reporter assay system for the detection of promoter or pathway activity.

• Signal transduction pathway analysis

Firefly luciferase is a 62kDa protein produced in nature by several species of the Lampyridae family of beetles, which includes the genera Photinus and Luciola. Thermo Scientific Red Firefly Luciferase has an emission range of 560-700nm (λmax = 613nm). Bioluminescent signal from firefly luciferase originates from the oxidation of D-Luciferin. Light output captured using a luminometer can be correlated with the amount of firefly luciferase protein produced and used to determine the activity of the promoter driving firefly luciferase expression. Firefly luciferase bioluminescence provides researchers with a non-radioactive assay for measuring transcriptional activity of regulatory elements. Firefly luciferase reporter activity can be used to determine promoter activity, to study upstream pathway activity in the cell, or to determine effect of activators or inhibitors.
