PRODUCT
Summary
HIF2 alpha antibody recognizes HIF2 alpha / EPAS1 protein, a transcription factor (predicted molecular weight of 97 kDa) induced by hypoxic conditions. It forms a heterodimer with HIF1 beta / ARNT to drive a specific gene expression profile in various physiological and pathological processes that occur in the context of hypoxia.
APPLICATION
Application Note
Recommended Starting Dilutions:
For WB: Use at a dilution of 1:100-1:3000. Recognizes a band at 118kDa.
For IHC: Use at a dilution of 1:100.
For ICC/IF: Use at a dilution of 1:100-1:1000.
Optimal dilutions/concentrations should be determined by the researcher.

Background
Hypoxia contributes significantly to the pathophysiology of major categories of human disease, 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 humans and endothelial cells of the embryonic and adult mouse, whereas HIF-1alpha functions primarily in extravascular tissues. HIF-2 alpha is also a potent activator of the tie-2 gene, which is known to be selectively expressed in endothelial cells. (1)
