Reporter Gene Analysis Firefly Luciferase Reporter Gene Assay

The most versatile and common reporter gene is the luciferase of the North American firefly photinus pyralis. The protein requires no posttranslational modification for enzyme activity. It is not even toxic in high concentration (in vivo) and can be used in pro- and eukaryotic cells.

AAT Bioquest's Amplite^® Luciferase Reporter Gene Assay Kits use a proprietary DTT-free formulation to quantify luciferase activity in live cells and cell extracts. The assay is based on firefly luciferase, a monomeric 61 kD enzyme that catalyses a two-step oxidation of luciferin, which yields light at 560 nm. Our formulation generates a luminescent product that gives strong luminescence upon interaction with luciferase. The kits provide all the essential components with an optimized "mix and read" assay protocol that is compatible with HTS liquid handling instruments. They have high sensitivity and can be used for the assays that require low detection limit. The kits have a fast, simple, and homogeneous bioluminescence assay for studying gene regulation and function. The assay is compatible with the use of standard cell growth media.
