Alternative Name HIF-2 alpha/epas1 (EPAS1 Antibody Abstract)
Background Hypoxia contributes significantly to the pathophysiology of major categories of humandisease, including myocardial and cerebral ischemia, cancer, pulmonary hypertension,congenital heart disease and chronic obstructive pulmonary disease.HIF-2 alpha is predominantly expressed in highly vascularized tissues of adult humansand endothelial cells of the embryonic and adult mouse, whereas HIF-1 alpha functionsprimarily in extravascular tissues. HIF-2 alpha is also a potent activator of the tie-2gene, which is known to be selectively expressed in endothelial cells. Alternate Names: anti-Endothelial pas domain protein 1 antibody, anti-Hif2a antibody, anti-Hypoxiainducible factor 2 alpha subunit antibody, anti-Member of pas superfamily 2 antibody,anti-MOP2 antibody, anti-EPAS1 antibody, anti-Hif-2a antibody, anti-Hif 2a antibody,anti-Hif 2 alpha antibody.
Gene Symbol: EPAS1
Gene ID 2034, 13819, 29452
UniProt Q99814
Application Notes This HIF-2 alpha (ep190b) antibody is useful for ELISA, Flow Cytometry, Immunohistochemistry on paraffin-embedded sections and Western Blot. In WB, it recognizes a band at ~118 kDa representing HIF-2 alpha.

. Wash cells in ice-cold PBS.
. Fix cells in formaldehyde (3.7 % in PBS) for 10 minutes at room temperature (RT).
. Wash cells twice, in PBS, and permeabilize by incubating in 0.2 % Triton X-100 in PBS for 10 minutes at RT.
. Incubate the slides with 1:1,000-1:3,000 dilution of anti-HIF-2 alpha for 1 hour at RT.
. Wash in PBS for 5 minutes.
. Incubate with HRP-conjugated goat anti-mouse for 30 minutes at RT.
. Detect binding using 3Prime-diaminobenzidine.
. Counterstain with hematoxylin.IHC-FFPE sectionsI. Deparaffinization: A. Treat slides with Xylene: 3 changes for 5 minutes each. Drain slides for 10 seconds between changes. B. Treat slides with 100 % Reagent Alcohol: 3 changes for 5 minutes each. Drain slides for 10 seconds between changes.II. Quench Endogenous Peroxidase: A. Place slides in peroxidase quenching solution: 15-30 minutes. To Prepare 200 mL of Quenching Solution: -Add 3 mL of 30 % Hydrogen Peroxide to 200 mL of Methanol.

Format Liquid
Concentration 1 mg/mL
Buffer PBS, Sodium Azide
Preservative Sodium azide
Precaution of Use WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
