Total cell lysates (15 µg protein) from Jurkat (Lane 1) cells were resolved by electrophoresis (4-20% Tris-Glycine gel), transferred to nitrocellulose, and probed with 0.025 µg/mL (1:20,000 dilution) Purified anti-NF-κB p50 Antibody, clone 4D1 (upper panel). Proteins were visualized by chemiluminescence detection using a 1:3000 diluted goat anti-mouse-IgG secondary antibody conjugated with HRP for anti-NF-κB p50 Antibody , or 1:5000 diluted Direct-Blot HRP anti-β-Actin Antibody, clone 2F1-1 (lower panel) as a loading control.

A549 cells were unstimulated (left panel) or treated with 20 ng/mL TNF-α (Cat. No. 717904, right panel) for 16 hours. Cells were then fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.5% Triton X-100 for 10 minutes, and blocked with 5% FBS for 60 minutes. Cells were then intracellularly stained with 2.0 µg/mL (1:250 dilution) of Purified anti-NF-κB Antibody, clone 4D1, overnight at 4°C, after which proteins were visualized with Alexa Fluor® 594 Goat anti-mouse IgG Antibody (Cat. No. 405326) at 2.0 µg/mL. Nuclei were counterstained with DAPI, and the image was captured with a 60X objective.

NF-κB p50 (nuclear factor kappa light chain enhancer in B cells p50, NF-κB1) is a member of the Rel/dorsal family. NF-κB is a transcription factor, originally identified as an activator of kappa light chain in B cells. NF-κB p50, together with another NF-κB subunit p65, binds to IκB inhibitor in cytoplasm as an inactive form. Phosphorylation of IκB releases NF-κB p50 and p65. Active form of NF-κB p50 and p65 then translocate to the nucleus and regulate target gene expression. Bacterial products and stimulation of a variety of receptors lead to NF-κB signal pathway activation. This 4D1 monoclonal antibody recognizes p105 (precursor of p50) and p50 (active form). 4D1 has been validated for Western blotting.
