LiveReport™ CRE Assay Kit

LiveReport™ CRE Assay Kit

The LiveReport™ CRE assay kit is a non-destructive solution for tracking cyclic AMP response element (CRE) binding protien (CRE) modulation in real-time.


Using the LiveReport™ CRE kit you can assay host cell CRE modulation continuously or repeatedly without perturbing the cells under study.


Cells treated with the LiveReport™ CRE assay kit continuously and automatically adjust their bioluminescent intensity to reflect real-time CRE modulation dynamics without any external stimulation required, providing a live stream of response data.

Easy To Use

The LiveReport™ CRE assay kit is a non-destructive solution for tracking cAMP response element (CRE) binding protein (CREB) modulation in real-time.

Using the LiveReport™ CRE kit you can assay host cell CRE modulation continuously or repeatedly without perturbing the cells under study.

Cells treated with LiveReport™ CRE assay mix express both luciferase and luciferin synthesis enzymes and continuously and automatically adjust their bioluminescent intensity to reflect real-time CRE modulation dynamics without any external stimulation required.

The LiveReport™ CRE assay mix can be transfected into cells using any standard method. After reagent uptake and expression, CRE modulation can be assayed repeatedly or continuously for up to one week or more, providing a live stream of response data.

Continuous, Automatic Performance

The LiveReport™ CRE assay mix contains:

    1. DNA for luciferase enzyme synthesis

    2. DNA for luciferin generation enzyme synthesis

    3. All external co-factors required for continuous bioluminescence

The supplied mixture is transfected into the cell to introduce the DNA for transcription/translation. Simultaneously, the co-factors are delivered into the medium for cellular uptake. Immediately after translation of the luciferin synthesis portion of the system, it will begin to scavenge cytosolically available components and convert them into luciferin for the bioluminescent reaction. The luciferin synthesis system has been specifically engineered so that the scavenging process does not impact cellular health or physiology. This ensures high data integrity and prevents luciferin synthesis from interfering with native metabolic processes.

The co-expressed luciferase enzyme requires luciferin (supplied by the luciferin synthesis complex), oxygen (available in abundance under routine culture conditions), and reducing power to produce light. Activation of the bioluminescent system is controlled by multiple CREs placed strategically upstream of a minimal promoter. When the CRE response factors are activated, light production is stimulated. The level of stimulation correlates with bioluminescent signal intensity, making it easy to quickly determine the timing, magnitude, and duration of stimulation.
