Highlights of Kit NFKB-3
  • Offers a visual demonstration of NF-kappa B activation and p65 translocation.
  • Kit provides matched primary and 2o fluorophore-tagged (rhodamine, Fab fragment) antibodies that detect p65 in nucleus and cytoplasm.
  • Applicable for most mammalian cells (e.g. human, mouse, rat, hamster, canine, rabbit, equine).
  • NF-kB activation is quantified by measuring immunofluorescence intensity of p65 using pixel quantification software.*
  • Sufficient solutions to label p65 in 40 microscope slides.


The NF-kB complex resides in the cytoplasm in its inactive state consisting of the inhibitory IkB subunit assembled with the p65-p50 heterodimer.  Upon stimulus, the IkB inhibitory subunit is ubiquitinated and degraded, exposing nuclear localization signals on the p65 (RelA) subunit, which then translocates into the nucleus.  The antibodies provided with this kit are employed to label p65 in nucleus and cytoplasm.  Fluorescent microscopy and pixel quantitation software are then employed to estimate the emission intensity of p65.

Methods Overview

Cells are grown on glass cover slips to approximately 85% confluency and treated to activate NF-kappa B.  Cellular proteins are first cross-linked and immobilized with paraformaldehyde (not provided).  The cross-linking reaction is quenched with a provided quenching solution.  Plasma and nuclear membranes are permeabilized with a provided solution that contains a permeabilization reagent and protein blockers.  An included anti-p65 IgG antibody is then applied to cells for 1hr.  Unbound antibody is washed away, and a provided rhodamine tagged Fab fragment secondary antibody is applied for 1 hr.   Unbound secondary antibody is washed away, and a sandwich consisting of slide and cover slip, with antifade solution in-between, is configured.  The antifade solution is allowed to solidify overnight.  The microscope slide-cover slip configuration is now ready for visual and quantitative detection of p65 translocation.
