    Total lysates (15 µg protein) from HepG2 (Human) and CHO (Hamster) were resolved by electrophoresis (4-20% Tris-glycine gel), transferred to nitrocellulose, and probed with 1:5000 (0.1 µg/ml) purified anti-IκB-α antibody, clone 3D6C02. Proteins were visualized using chemiluminescence detection by incubation with HRP Goat anti-Mouse secondary antibody (Cat. No. 405306, 1:3000 dilution). Direct-Blot™ HRP anti-β-actin antibody was used as a loading control (Cat. No. 643807, 1:8000 dilution).

    Hela cells were fixed with cold methanol at -20°C for 15 minutes and blocked with 5% FBS for 60 minutes. The cells were then intracellularly stained with (A) 2 µg/ml anti-mouse IgG2b, κ or (B) 2 µg/ml IκB-α antibody (clone 3D6C02), (C) 0.5 µg/ml IκB-α antibody (clone 3D6C02), or (D) 0.2 µg/ml IκB-α antibody (clone 3D6C02), and incubated overnight at 4°C followed by 2µg/ml (1:250) Alexa Fluor® 594 (Red) goat anti-mouse IgG for one hour at room temperature. Nuclei were counterstained with DAPI (Blue). The image was captured with a 60X objective. Exposure times: (A) 1/30, (B) 1/50, (C) 1/50, (D) 1/50.

Description

IκB-α is an inhibitory protein that binds to the NF-κB complex and retains this complex in the cytoplasm where it cannot activate transcription. Upon cellular stimulation, the IκB proteins are phosphorylated and degraded via the ubiquitin pathway allowing for nuclear translocation of NF-κB. The NF-κB complex can then bind DNA to activate gene expression of multiple proteins involved in inflammation, cellular proliferation, differentiation, and apoptosis.

Application

WB - Quality tested
ICC - Verified
Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.1 - 0.5 µg/ml (1:1000 - 1:5000 dilution). For immunocytochemistry, the suggested use is 0.5 - 1.0 µg/ml (1:500-1:1000 dilution). It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This antibody weakly reacts with mouse and rat. Based on in-house testing, clone 3D6C02 does not block clone 25/IkBa/MAD-3, and only partially blocks L35A5 also raised against I?B-a.

Antigen Details

Structure
Inhibitory protein of the NF-κB complex that contains multiple ankyrin repeats.
Distribution

Cytoplasm

Function
Regulates transcriptional activity of NF-κB by binding the complex and trapping it in the cytoplasm. Serine phosphorylation of IκB targets it for destruction via the ubiquitination pathway, which allows the NF-κB complex to translocate to the nucleus.
Interaction
NFkB1, SUMO4, p53, ribosomal S6 kinase 1
