Protocol Available protocols: Western Blotting, Immunoprecipitation Specificity / Sensitivity HIF-2 alpha (E2N9W) Rabbit Monoclonal Antibody recognizes endogenous levels of total HIF-2α protein. This antibody does not cross-react with HIF-1α protein. Species Reactivity: Mouse, Rat Source / Purification Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the carboxy terminus of mouse HIF-2α protein. Background Hypoxia-inducible factor (HIF) is essential for the cellular response to hypoxia (1,2). Under normoxia conditions, the α subunit of HIF is ubiquitinated by von Hippel-Lindau (VHL) protein and is degraded in the ubiquitin/proteasome pathway (1,2). Hypoxia inhibits degradation of the α subunit, which leads to its stabilization (1,2). HIF, in turn, regulates the transcription of a variety of genes that respond to hypoxia conditions (1,2). There are several isoforms of the HIF α subunit (2). Studies have found that HIF-1α and HIF-2α expression is increased in some human cancers (2). HIF-1α has both pro- and anti-proliferative activities, whereas HIF-2α does not possess anti-proliferative activity (2). Therefore, HIF-2α likely plays an important role in tumorigenesis (2,3).
