The Pierce™ Firefly Luciferase Glow Assay Kit provides a bright and stable bioluminescence signal (half-life greater than 2 hours) in the presence of firefly luciferase reporters for protein expression assays.

• Highly sensitive detection of firefly luciferase activity
• Increased signal stability
• Contains a universal cell lysis buffer and optimised glow assay reagent

The bioluminescent signal produced by firefly luciferase results from the oxidation of D-Luciferin. The Firefly Luciferase Glow Kit produces an extended light signal correlating with the amount of firefly protein expressed, which is proportional to the activity of the promoter for firefly expression.
