Whole cell extracts (15 µg total protein) from the indicated cell lines were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 0.25 µg/mL purified anti-NF- κB p65 (clone A21012A) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-mouse IgG (Cat. No. 405306) at a 1:3000 dilution. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426319) was used as a detection agent. Direct-Blot™ HRP anti-GAPDH (Cat. No. 607904) was used as a loading control at a 1:50000 dilution. Lane M: Molecular weight marker

    IHC staining of purified anti-NF- κB p65 (clone A21012A) on formalin-fixed paraffin-embedded human colon tissue. Following antigen retrieval using Tris EDTA, the tissue was then incubated without (panel A) or with (panel B) anti-NF- κB p65 (clone A21012A), followed by incubation with 10 µg/mL of Alexa Fluor® 647 goat anti-mouse IgG (Cat. No. 405322) for 1 hour at room temperature. Nuclei were counterstained with DAPI (Cat. No. 422801). Images were captured with a 60X objective. Scale bar: 50 µm

Cells were then stained with 5.0 µg/mL purified mouse IgG1, κ isotype control (Cat. No. 400102) (panel A) or with 5.0 µg/mL of purified anti-NF- κB p65 (clone A21012A) (panel B), followed by incubation with 2.5 µg/mL of Alexa Fluor® 594 goat anti-mouse IgG (Cat.

    HeLa cells were fixed with Fixation Buffer (Cat. No. 420801), permeabilized using True-Phos™ Perm Buffer (Cat. No. 425401), and intracellularly stained with anti-NF- κB p65 (clone A21012A) (filled histogram) or purified Mouse IgG1, κ isotype control (Cat.

Description

NF-κB p65, also known as NFKB3 and RelA, is one of five members of the nuclear factor kB (NF-kB)/Rel family. Inactive NF-κB p65 is sequestered in the cytoplasm as a complex with IκB inhibitory proteins. Upon activation of the NF-κB pathway, IκB proteins are degraded, thus releasing NF-κB p65 to the nucleus. Binding of NF-κB p65 to transcriptional cofactors is induced via phosphorylation on serines 276, 529, 536, and 471. As a transcription factor, NF-κB p65 is vital to cell proliferation, immune response, survival, and apoptosis. Through regulation of chondrocyte and osteoblast differentiation and survival, NF-κB p65 has a crucial role in skeletal development. Overexpressed in several cancers, NF-κB p65 functions as an oncogene and has been implicated in tumorigenesis, metastasis, tumor angiogenesis, and chemoresistance.

Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.25 - 0.50 µg/mL. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 1.0 - 10.0 µg/mL is suggested. For immunocytochemistry, a concentration range of 1.25 - 5.0 μg/mL is recommended. For flow cytometric staining, the suggested use of this reagent is ≤ 0.125 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application

Application Notes

When testing by ICC, we recommend fixation with 4% PFA followed by permeabilization with Triton X-100 or ice-cold methanol.
