Product Overview
Clone 28H19 is a rabbit monoclonal antibody that recognizes hepatocyte nuclear factor 4-alpha (gene HNF4A) in human, mouse and rat samples and is validated for Western blot, IHC and immunoprecipitation. The predicted molecular weight is 52.8 kDa, and the supplier reports an observed band at about 53 kDa.
HNF-4α (HNF4A) is a nuclear receptor transcription factor that is a master regulator of gene expression in liver, intestine, kidney and pancreatic islets. It controls genes for lipid, glucose and drug metabolism and helps establish liver identity during development. HNF4A mutations cause MODY1, and the protein is a standard hepatocyte and intestinal marker.

Samples with a confirmed band (WB): human HepG2 cells, human Caco-2 cells, human A549 cells, human HeLa cells, rat liver tissue, mouse liver tissue.
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 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human colon cancer tissue, human stomach cancer tissue, mouse liver tissue, rat liver 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
Synthetic peptide based on the sequence of human HNF-4-alpha.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places hepatocyte nuclear factor 4-alpha in the nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
