The RelA p65 NF-kB (NF-kappa B, NF-{kappa}B) ELISA kit employs the sandwich ELISA(96T) format to quantitate NF-kB p65 protein levels.  The 96-well strip plate is coated with an affinity purified polyclonal capture antibody selective to the RelA (p65) subunit of NF-kB.  After addition of sample, incubation and wash, a second polyclonal anti-RelA (p65) HRP-conjugated antibody is added to each well.  Color reagents are added to generate a colorimetric reaction, which corresponds to the concentration of RelA (p65) in the sample.

A Nuclear-Cytoplasmic fractionation kit is offered to partition cytoplasmic and nuclear p65.  p65(RelA) in the nuclear and cytoplosmic fractions can be directly measured with this kit to provide an estimate of NF-kappa B activation by calculation of the nuclear p65 relative to cytoplasmic p65 concentration ratio.
