Detection of Human HIF‑2 alpha /EPAS1 by Western Blot. Western blot shows lysates of 786‑O human renal cell adenocarcinoma cell line (HIF‑2 alpha positive), Caki‑2 human clear cell carcinoma epithelial cell line (HIF‑2 alpha negative), and HeLa human cervical epithelial carcinoma cell line (HIF‑2 alpha negative). PVDF Membrane was probed with 1 µg/mL of Human HIF‑2 alpha /EPAS1 Monoclonal Antibody (Catalog # MAB2886) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for HIF‑2 alpha /EPAS1 at approximately 110 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: HIF-2 alpha/EPAS1
The hypoxia-inducible transcription factor 2 alpha (HIF-2 alpha ) is stabilized in hypoxic tissue and, similarly to HIF-1 alpha, complexes with Aryl hydrocarbon receptor nuclear translocator (ARNT). Both the HIF-1 and HIF-2 complexes bind hypoxia-response elements (HREs) in the promoters of many genes involved in adapting to an environment of insufficient oxygen or hypoxia. HIF-1 and HIF-2 do not appear completely redundant. Hypoxic tissue environments occur in vascular and pulmonary diseases as well as cancer, which illustrates the potentially broad impact of gene regulation by both HIF-1 alpha and HIF-2 alpha
