pNiFty2 - NF-κB reporter plasmids (Blasticidin Resistance)

NF-κB-inducible reporter plasmids with Blasticidin resistance

ABOUT

NF-κB-inducible reporter plasmids - ELAM promoter - Blasticidin resistance 

InvivoGen has designed pNiFty2, a collection of inducible reporter plasmids, to monitor pattern recognition receptor (PRR) activation and cytokine signaling through the inducible expression of reporter genes.

The pNiFty2-N plasmids feature an NF-κB-inducible reporter gene under the control of an engineered ELAM (endothelial cell-leukocyte adhesion molecule) promoter. This promoter comprises five NF-κB repeated transcription factor binding sites (TFBS) to enhance NF-κB-mediated transcription [1].

The reporter genes encode either:

  • SEAP (secreted alkaline phosphatase),
  • Lucia luciferase (secreted),
  • Firefly luciferase (intracellular), or
  • Renilla luciferase (intracellular). ​

These four pNiFty2-N 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 Puromycin or Zeocin® resistance, see table below:

Reporter genes

• SEAP is a secreted form of human embryonic alkaline phosphatase. It is extremely heat stable and resistant to the inhibitor L-homoarginine. It catalyzes the hydrolysis of pNitrophenyl phosphate (pNpp) producing a yellow end product. SEAP levels can be evaluated qualitatively with the naked eye and quantitatively using a spectrophotometer at 405 nm in combination with SEAP detection media, such as HEK-Blue™ Detection or QUANTI-Blue™ Solution, a SEAP detection reagent.

• Lucia is a secreted coelenterazine luciferase encoded by a synthetic gene developed by InvivoGen. It generates 1000-fold higher bioluminescent signal compared to the commonly used Firefly and Renilla luciferases. Lucia luciferase activity can be evaluated using QUANTI-Luc™ 4 Lucia/Gaussia, an assay reagent containing all the components required to quantitively measure the activity of Lucia luciferase and other coelenterazine-utilizing luciferases.

• The firefly luciferase (Fluc) gene encodes for an intracellular luciferase of fireflies and click beetles. This enzyme interacts with D-luciferin as a chemiluminescent substrate to produce light emission peaking at 560 nm. After cell lysis, the reaction can be measured and detected simply, rapidly, and with good sensitivity by means of a luminescence-measuring instrument.

• The Renilla luciferase (Rluc) gene encodes for an intracellular luciferase from the sea pansy renilla reniformis. This enzyme catalyzes coelenterazine oxidation leading to bioluminescence and the production of light emission peaking at 480 nm. After cell lysis, the activity can be evaluated using QUANTI-Luc™ 4 Renilla, an assay reagent containing all the components required to quantitively measure the activity of Renilla luciferase and other coelenterazine-utilizing luciferases.
