ICFC - Quality tested

Recommended Usage:

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining using our nuclear factor staining protocol. For flow cytometric staining, the suggested use of this reagent is 5 µl per million cells or 5 µl per 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

Human lung adenocarcinoma epithelial cell

Human lung adenocarcinoma epithelial cell line A549 was fixed and permeabilized with Nuclear Factor Fixation and Permeabilization Buffer Set , and then stained with NF-κB p65 (clone 14G10A21) APC (filled histogram) or mouse IgG2b, κ APC isotype control (open histogram).


NF-κB p65 is a member of REL-like domain containing protein family, which forms a NF-κB complex with the other family members: NF-κB1 (p105/p50) or NF-κB2 (p100/p52). The NF-κB complex is inactivated and held in the cytoplasm by the NF-κB inhibitor IκB. In response to activation stimuli, IκB kinases (IKKs) phosphorylates IκB, resulting in degradation of IκB and liberation of NF-κB complex. The activated NF-κB complex translocates to the nucleus and binds to κB sites in the DNA of their target genes.

Other Names: Nuclear factor NF-kappa-B p65 subunit (NF-κB p65), Rel-A, transcription factor p65, Nuclear factor of kappa light polypeptide gene enhancer in B-cells 3 (NFKB3)
Structure: 65 kD protein containing a Rel homology domain (RHD), an activation domain, and a 9aaTAD domain.
Distribution: The inactivated NF-κB complex containing p65 subunit is bound to IκB and is localized to cytoplasm. Upon activation, I-κB is phosphorylated and degraded. The activated NF-κB complex is in turn translocated to the nucleus as a transcription factor.
Function: NF-κB is a homodimeric or heterodimeric complex formed by the Rel-like domain-containing proteins. The most abundant form is p65 (RelA) - p50 (NF-κB1) heterodimer complex. The NF-κB complex is a ubiquitously expressed transcription factor which is involved in various biological functions, such as cell growth, tumorigenesis, differentiation, apoptosis, inflammation, and immune responses.
Interaction: Interacts with NF-κB1 (p105/p50) or NF-κB2 (p100/p52) to form heterodimeric NF-κB complex. Interacts with HDAC1, HDAC3, and CBP. Interaction with MEN1 inhibits transactivation activity of NF-κB complex.
