Fluorescent protein promoter reporters: on-demand reporting

On-demand reporter vectors are the next generation of promoter reporters. With these reporter systems, you can compensate effectively for reporter background without compromising your assay’s signal intensity. Low background and a bright signal are no longer mutually exclusive.

The challenges: overcoming high background & low signal intensity

Traditional promoter reporter assays generally struggle with the fact that most promoters are not very “tight”. As a result, your promoter of interest may drive reporter expression even without being activated—for example, during the time between transfection and the start of your experiment. These preexisting reporter molecules (the background) are the main cause of a low signal-to-noise ratio after promoter induction during the actual experiment.

One previous approach to this problem was to modify reporters for very quick, constitutive degradation. However, because these reporters are constitutively degraded as soon as they are made, it is impossible to accumulate a large quantity of reporter molecules inside the cell, even upon promoter activation. As a result, only a fraction of the reporter molecules are present long enough to be measured, and this type of assay has low signal intensity.

The solution: reporters on demand

The On-Demand Living Colors Fluorescent Protein Reporter Systems meet the challenge by providing both a low background and a broad dynamic range. This versatility is possible because they use a combination of technologies: each system includes a bright fluorescent protein reporter (AmCyan1, tdTomato, or ZsGreen1) for high signal intensity, coupled with ligand-dependent ProteoTuner protein stabilization/destabilization technology to eliminate background.

In these systems, the fluorescent protein reporter is expressed as a fusion protein tagged on its N-terminus with a ligand-dependent destabilization domain (DD). The DD rapidly targets the reporter protein for proteasomal degradation, guaranteeing a low reporter background signal at the start of your experiment. However, when the small, membrane-permeant ligand Shield1 is added to the sample, it binds to the DD and protects the reporter from degradation, so that it can accumulate.

By adding Shield1 simultaneously with your candidate inducer, you can effectively stabilize the reporter protein when it is synthesized in response to promoter activation. The majority of the fluorescent protein reporter molecules expressed during promoter activation will contribute to your readout, allowing for a considerably higher dynamic range and drastically improved signal-to-noise ratio compared to other types of reporter systems.

	On-demand fluorescent protein reporter systems	Traditional reporter systems
Background	Uniformly low	Promoter-dependent; may be high
Signal	Bright	Reporter-dependent. If background is low, signal is usually dim
Signal-to-noise ratio	High, due to bright signal and low background	Often low, especially when background is low
Studying timely promoter activity by eliminating unwanted reporter molecules	Easy—simply remove Shield1 reagent	Difficult; depends on reporter's natural lifespan

High signal, low background

In order to demonstrate the high signal-to-noise ratio and wide dynamic range of the DD fluorescent protein reporter systems, we compared the fold induction achieved using the DD-fluorescent protein reporters with that achieved using regular (non-destabilized) fluorescent proteins. The DD-tagged reporters stabilized by Shield1 had a much wider dynamic range, and therefore a much larger fold increase in the signal than the untagged versions of the same reporters. For the untagged versions, we observed high background fluorescence from reporter molecules that accumulated prior to induction, which drastically reduced the fold increase in signal intensity.

Choose your on-demand reporter system

Our on-demand reporter systems each consist of the necessary vectors (red, green, or cyan) plus Shield1.

Flexible choices

Use the DD fluorescent protein reporter systems to monitor any promoter of interest—just insert your promoter of interest upstream of the DD reporter. Choose from plasmid or lentiviral vector formats.

CRE DD Cyan Reporter System

Each

USD $569.00

License Statement

ID Number
57	This product is covered by U.S. Patent No. 8,173,792.

The CRE DD Cyan Reporter System is designed to monitor cAMP response element binding protein (CREB) activity in mammalian cells, with minimal background signal. It includes the pCRE-DD-AmCyan1 Reporter vector and Shield1.

pCRE-DD-AmCyan1 encodes a cyan fluorescent protein reporter tagged at its N-terminus with the ProteoTuner destabilization domain (DD), and under the control of the CRE promoter. The DD causes the DD-AmCyan1 reporter to be rapidly targeted to and degraded by proteasomes. This minimizes background fluorescence from leaky promoters prior to promoter activation.

To monitor CREB activity, a candidate inducer is added to the medium simultaneously with the DD's stabilizing ligand, Shield1. This allows DD-AmCyan1 to accumulate in response to CREB activation. As a result, only the reporter molecules expressed during CRE induction contribute to the fluorescence signal. This system provides a considerably higher signal-to-noise ratio than can be obtained with non-destabilized or constitutively destabilized reporter systems.

The Lenti-X DD Red Reporter System includes the Lenti-X DD-tdTomato Vector Set and Shield1. The Lenti-X DD-tdTomato Vector Set includes two lentiviral expression vectors (a reporter vector and a control vector) that produce high titers of recombinant lentivirus, which can efficiently transduce both dividing and nondividing mammalian cells. The system provides enough reagents for 16 packaging reactions. The pLVX-DD-tdTomato Reporter Vector is a promoterless vector that allows you to insert your promoter of interest upstream of the red fluorescent protein tdTomato, tagged at its N-terminus with the ProteoTuner destabilization domain (DD). In the absence of the membrane-permeant ligand Shield1, the DD causes the reporter protein to be rapidly targeted to and degraded by proteasomes. This very efficient and controllable destabilization method minimizes reporter background fluorescence from leaky promoters prior to promoter activation. To analyze promoter activity, a candidate inducer is added to the medium along with Shield1, which binds to the DD tag and thereby stabilizes the reporter protein and allows it to accumulate. As a result, only the reporter molecules expressed during promoter induction will contribute to the fluorescence signal, providing a considerably higher signal-to-noise ratio than that obtained with nondestabilized or constitutively destabilized reporter systems. Cells used to monitor uninduced promoters (e.g., the negative control) will be treated with Shield1 alone.

57	This product is covered by U.S. Patent No. 8,173,792.

The NF_kB DD Cyan Reporter System is designed to monitor NF_kB activation in mammalian cells, with minimal background signal. It includes the pNFkB-DD-AmCyan1 Reporter vector and Shield1.

pNF_kB-DD-AmCyan1 encodes a cyan fluorescent protein reporter tagged at its N-terminus with the ProteoTuner destabilization domain (DD), and under the control of the NF_kB promoter. The DD causes the DD-AmCyan1 reporter to be rapidly targeted to and degraded by proteasomes. This minimizes background signal from leaky promoters prior to promoter activation.

To monitor NF_kB activity, a candidate inducer is added to the medium simultaneously with the DD's stabilizing ligand, Shield1. This allows DD-AmCyan1 to accumulate in response to NF_kB activation. As a result, only the reporter molecules expressed during NF_kB induction contribute to the fluorescence signal. This system provides a considerably higher signal-to-noise ratio than can be obtained with non-destabilized or constitutively destabilized reporter systems.
