Product Overview
This rabbit polyclonal antibody detects SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily B member 1 (gene SMARCB1) in human, mouse and rat samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 44.1 kDa, and the supplier reports an observed band at about 44 kDa.
SMARCB1 (also called INI1, SNF5 or BAF47) is a core subunit of SWI/SNF (BAF) chromatin remodeling complexes, which control gene expression by moving nucleosomes. It is a well-known tumor suppressor: loss of SMARCB1 drives malignant rhabdoid tumors, and loss of nuclear staining is widely used in pathology research.

Validated Applications
| Western blot | 0.05–0.25 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HepG2 cells, human K562 cells, human Jurkat cells, human 293T cells, rat brain tissue, mouse brain tissue, mouse NIH3T3 cells, mouse Neuro-2a cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.167 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human tonsil tissue, human cerebral cortex 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 SNF5/SMARCB1 fragment (Glu105–Asp358), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily B member 1 in the nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
