InvivoGen has designed the pNiFty plasmid collection to monitor pattern recognition receptor (PRR) and cytokine signaling through the inducible expression of reporter genes. Two families of pNiFty plasmids are available:

— pNiFty2-N family: NF-κB-inducible reporter plasmids
— pNiFty3-I family: IRF-inducible reporter plasmids

All pNiFty plasmids are composed of the following three key elements:

a proximal promoter,
repeated transcription factor binding sites (TFBS), and
an inducible reporter gene encoding either for SEAP (secreted alkaline phosphatase) or luciferases, including Lucia, Firefly, or Renilla.

pNiFty2 family:

The pNiFty2-N plasmids feature an engineered ELAM (endothelial cell-leukocyte adhesion molecule) promoter combined with NF-κB TFBS to enhance the NF-κB-mediated transcription [1]. These pNiFty2-N plasmids are selectable with Zeocin® in both E. coli and mammalian cells and can be used to generate stable clones. They are also available with either Blasticidin or Puromycin resistance.

pNiFty3 family:

The pNiFty3-I plasmids feature the mouse IFN-β minimal promoter combined with several ISRE (interferon responsive elements) TFBS to enhance the IRF-mediated transcription [2]. These pNiFty3 plasmids are selectable with Blasticidin in both E. coli and mammalian cells and can be used to generate stable clones. They are also available with either Zeocin® or Puromycin resistance.

► pNifTy2-N and pNiFty3-I families allow you to generate your own Dual reporter cell lines for the simultaneous monitoring of NF-κB and IRF activation, using the combination of reporter and antibiotic resistance genes that suits you best.

Advantages of pNiFty plasmids:

Large choice of reporter genes encoding for SEAP or luciferases, including Lucia, Firefly, or Renilla
Available with different antibiotic resistances: Zeocin®, Blasticidin, and Puromycin
Selectable in both E.coli and mammalian cells
Suitable for the generation of stable clones
Combined use of pNiFty2-N and pNiFty3-I for simultaneous monitoring of NF-κB and IRF signaling

For your convenience, InvivoGen also provides the reporter detection reagents QUANTI-Blue™, QUANTI-Luc™ 4 Gaussia/Lucia, and QUANTI-Luc™ 4 Renilla to measure SEAP, Lucia, and Renilla activities, respectively.
