Application Notes
Please note that this kit has not yet been tested or used with any of the reporter cell lines and is therefore not guaranteed for detection of the target protein these samples. Contains reagents and protocol to prepare whole, nuclear, and cytoplasmic cell fractions. Multiple samples can be analyzed in a low-volume, high-throughput format. Full analysis complete in just hours. Allows direct measurement of changes in p65 translocation. Allows study of NF-kB activation without gel-shift assay. [This product is the same as Imgenex's NF-kappaB p65 ActivELISA Kit, IMK-503].

Activation of the NF-kB pathway can be triggered by many factors including TNFalpha, UV, IL-1, lipopolysaccharide (LPS), mitogens, and phorbol esters. NF-kB is controlled by a family of inhibitory proteins called, IkBs. IkB proteins are phosphorylated by IkB kinase complex consisting of at least three proteins, IKK1/alpha, IKK2/Beta, and IKK3/gamma. External stimuli such as tumor necrosis factor or other cytokines initiate a signal transduction cascade that leads to the activation of IkB-kinase complex, which then specifically phosphorylates IkBalpha on Serine-32 and Serine-36. Phosphorylation of these sites leads to ubiquitination of IkBalpha and subsequent degradation by the 26 S proteasome. Degradation of IkBalpha results in unmasking of the nuclear localization signal of NF-kB dimers, which subsequently translocates to the nucleus and acts as a transcription factor for genes controlling inflammatory cytokines, adhesion molecules, and other proteins. Thus the nuclear levels of p65 may correlate positively with the activation of NF-kB pathway.
