NanoLuc® Reporter Vector with NF-κB Response Element

The pNL3.2.NF-κB-RE[NlucP/NF-κB-RE/Hygro] Vector contains five copies of an NF-κB response element (NF-κB-RE) that drives transcription of a destabilized form of NanoLuc® luciferase, an engineered small (23.3kDa) luciferase fusion protein. The NlucP reporter consists of NanoLuc® luciferase with a C-terminal fusion to PEST, a protein destabilization domain, which responds more quickly and with greater magnitude to changes in transcriptional activity than unmodified NanoLuc® luciferase.

NanoLuc® (Nluc) luciferase is a small enzyme (19.1kDa) engineered for optimal performance as a luminescent reporter. The enzyme is about 100-fold brighter than either firefly (Photinus pyralis) or Renilla reniformis luciferase using a novel substrate, furimazine, to produce high intensity, glow-type luminescence. The luminescent reaction is ATP-independent and designed to suppress background luminescence for maximal assay sensitivity.

About the NanoLuc® Luciferase Reporter Enzyme

NanoLuc® luciferase in the form of NanoLuc®-PEST (NlucP) closely couples protein expression to changes in transcriptional activity and increased signal-to background ratios. The PEST sequence appended to Nluc destabilizes the reporter protein, make NanoLuc® luciferase more responsive to changes in the cell. Luminescence is linearly proportional to the amount of NanoLuc® protein over a 1,000,000-fold concentration range, with a signal half-life ≥2 hours when detected with Nano-Glo® Luciferase Assay Reagent.

NanoLuc® luciferase possesses a number of physical properties that make it an excellent reporter protein:

  • very small, monomeric enzyme (171 amino acids; 513bp)
  • high thermal stability (Tm = 60°C)
  • active over a broad pH range (pH 6–8)
  • no post-translational modifications or disulfide bonds
  • uniform distribution in cells
  • emission spectrum well suited for bioluminescence resonance energy transfer (BRET; λmax = 465nM).

NanoLuc® luciferase is made available in a variety of plasmids designed for use in reporter gene assays of transcriptional control and with each of the NanoLuc® forms (unfused Nluc, PEST destabilized NlucP, and secreted secNluc). The different pNL variations are designed for the following:

  • pNL1: cloning of a known or putative promoter region
  • pNL2: cloning of a known or putative promoter region and establishment of a stable cell line through Hygromycin selection
  • pNL3: cloning of a binding site or response element not in need of a basic promoter (such as are present in the pNL3.2.NF-κB-RE vector)
  • Control plasmids for the unfused, PEST-destabilized and secreted Nluc forms also are available.

The pNL vector series uses a pGL4-based backbone for easy sequence transfer from existing plasmids. This backbone design also reduces anomalous results by removing many transcription factor binding sites and other potential regulatory elements. The NlucP gene is codon optimized and has had many potential regulatory elements or other undesirable features removed (such as common restriction enzyme sites).

BY USE OF THIS PRODUCT, RESEARCHER AGREES TO BE BOUND BY THE TERMS OF THIS LIMITED USE LABEL LICENSE. If researcher is not willing to accept the conditions of this limited use statement, and the product is unused, Promega will accept return of the unused product and provide researcher with a full refund.

Researchers may use this product for research use only; no transfer or commercial use of this product is allowed. Commercial use means any and all uses of this product or derivatives by a party in exchange for consideration, including, but not limited to (1) use in further product manufacture; (2) use in provision of services, information or data; and (3) resale of the product or its derivatives, whether or not such product or derivatives are resold for use in research. Researchers shall have no right to modify or otherwise create variations of the nucleotide sequence of the luciferase gene except that researcher may (1) create fused gene sequences provided that the coding sequence of the resulting luciferase gene has no more than four deoxynucleotides missing at the affected terminus compared to the intact luciferase gene sequence; and (2) insert and remove nucleic acid sequences in splicing research predicated on the inactivation or reconstitution of the luminescence of the encoded luciferase. No other use of this product or derivatives is authorized without the prior express written consent of Promega.

In addition, researchers must:
(1a) use Nano-Glo®-branded luminescent assay reagents (LARs) for all determinations of luminescence activity of this product and its derivatives; or
(1b) contact Promega to obtain a license for use of the product and its derivatives with LARs not manufactured by Promega.

For uses of Nano-Glo®-branded LARs intended for energy transfer (such as bioluminescence resonance energy transfer) to acceptors other than a genetically encoded autofluorescent protein, researchers must:
