Product Overview
This rabbit polyclonal antibody targets nuclear factor NF-kappa-B p100 subunit (gene NFKB2) in human, mouse and rat samples and is validated for IHC and Western blot. The predicted molecular weight is 96.7 kDa; the supplier reports observed bands at 52 kDa (active form), 120 kDa (precursor).
NFKB2 encodes p100, a precursor that is processed to the p52 subunit of NF-κB. Processing of p100 to p52 is the hallmark of the non-canonical NF-κB pathway, which is triggered by receptors such as BAFF-R, CD40 and LTβR and is important for lymphoid organ development and B-cell maturation. Antibodies that detect both forms help follow this processing step.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse) |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL (Human, Mouse, Rat) |
Samples with a confirmed band (WB): human HeLa cells, human Jurkat cells, human MCF-7 cells, human A549 cells, human U87 cells, mouse lung tissue, mouse RAW264.7 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): rat intestine tissue, human lung cancer tissue, human mammary cancer tissue, mouse intestine tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant human NFkB p100/p52 fragment (Met1–Arg340), expressed in E. coli. Sequence identity with the mouse ortholog: 96%.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places nuclear factor NF-kappa-B p100 subunit in the nucleus and cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
