HNF1B (hepatocyte nuclear factor 1 β), a homeodomain, is an atypical POU (Pit-1, Oct-1, andUnc-86) transcription factor which is associated with the early vertebrate development and embryonic survival. It is expressed in the pancreas, kidney, lung, ovary, testis, and throughout the gastrointestinal tract.

Immunocytochemistry (1 paper)
Anti-HNF1B antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
The expression of HNF1B (hepatocyte nuclear factor 1 β) is upregulated in papillary renal cell tumours (RCTs) as well as in some conventional RCCs, renal oncocytomas, chromophobe RCCs and normal kidneys. On the other hand, its expression is suppressed in Wilms′tumours. It is a nuclear protein required for liver-specific expression. It can binds to the promoters and enhancers of a variety of genes expressed in liver along with the proximal element (PE) of the albumin gene.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.
Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
