Luciferase is the general term given to a class of oxidative enzymes that catalyze reactions that give off light, a process known as bioluminescence. In biology, researchers can take advantage of this reaction and use it as a readout for various biological processes. This has perhaps been exploited most in luciferase reporter cell lines where a promoter region from a gene of interest is placed immediately upstream of the coding sequence for luciferase. In this system, transcriptional activation of the gene of interest leads to a level of luciferase expression that is proportional to the level of gene activation.

The level of activation is then assessed by lysing the cells and adding the luciferase substrate, D-luciferin. Using the One-Step Luciferase Assay System from BPS Bioscience, this is accomplished in a single step as the lysis buffer has been formulated with D-luciferin. After a brief incubation period, bioluminescence is read on a luminometer.


The One-Step Luciferase Assay System is designed to be used for high-throughput, sensitive quantitation of firefly luciferase activity in mammalian cell culture. The reagent consists of two components, a Luciferase Reagent Buffer (Component A) and Luciferase Reagent Substrate (Component B). Component A and Component B are combined to form a working solution that contains all the necessary components for cell lysis and luciferase quantitation. This assay system has several features: 

• Sensitive – highly sensitive detection of firefly luciferase activity. 
• Stable – the signal output is stable for more than two hours, providing flexibility with regard to incubation time 
• Convenient – simple one-step, homogeneous protocol. 
• High-throughput – one-step homogeneous protocol minimizes handling steps to support high-throughput screening applications 
• Compatibility – works well with a variety of common media containing 0-10% serum and phenol red. 
• Instrumentation – does not require a luminometer with injectors.

Instructions for use:
See product datasheet for detailed protocol.
Storage / Stability:
At least 6 months when stored as directed. Upon first thaw, store in aliquots at -20°C. The reagent may be subjected to several freeze/thaw cycles with no effect on functionality, but it is recommended that freeze/thaw cycles be avoided whenever possible.
• Monitor firefly (Photinus pyralis) luciferase activity in cultured mammalian cells. • High-throughput screening using luciferase reporter cell lines

• The reagent has been validated in a 96-well format. Other formats will require scaling and optimization by the end-user. 
• Luciferase Reagent Buffer must be at ~ room temperature (20- 25°C) before use. 
• Luciferase Assay Reagent should be added to cells for at least 5 minutes before measuring luminescence to allow complete cell lysis. 
• For maximal light intensity, measure samples within 1 hour of reagent addition.
• Avoid exposing to excessive heat or light during incubation.
• Different cell lines may exhibit variation in lysis ability and/or luminescence signal and may require slight optimization by the end-user.
• Luminescence signal is affected by assay conditions. Results should be compared between samples measured using the same cell type and media/serum combinations.
• To analyze multiple plates, include a common control sample in each plate and normalize the luminescence of each plate to the control contained in the same plate.
• Background luminescence is a characteristic of luminometer performance, therefore, background luminescence must be subtracted from all readings for accuracy.

Protect from light. Avoid freeze/thaw cycles.
