Interpolated concentrations of native HIF-2-alpha in DFO treated Human HeL1 cell extract, sample based on a 250 μg/mL extract load.

HELA cells were untreated or treated with 250 μM DFO for 24 hrs, then collected and extracted according to sample preparation protocol (see section 11.1). The concentrations of HIF-2-alpha were measured in duplicate and interpolated from the HIF-2-alpha standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean HIF-2-alpha concentration was determined to be 520 pg/mL in DFO treated HELA cell extract and undetectable in untreated HELA cell extract.

Dose-dependent induction of HIF-2-alpha in HELA cells by deferoxamine (DFO).

HeLa cells were cultured in 96-well tissue culture plates and were either untreated (Vehicle Control) or exposed to varying doses of DFO for 24 hours (DFO treated). Cells were extracted directly in the culture plate by overlaying culture media with Cell Extraction Buffer PTR with Enhancer such that the final concentration was 1X Cell Extraction Buffer PTR. Extracts were applied to the HIF-2-alpha SimpleStep ELISA plate. Raw data and standard deviation is plotted from quadruplicate measurements.

Product details

Human HIF-2-alpha ELISA Kit (ab227898) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of HIF-2-alpha protein in cell culture extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human HIF-2-alpha with 19 pg/ml sensitivity.

SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:

- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips

A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Supplementary information

HIF-2-alpha also known as hypoxia-inducible factor 2-alpha or EPAS1 plays a significant role in cellular response to oxygen levels. Mechanically HIF-2-alpha functions as a transcription factor that activates certain genes when oxygen is low. The protein typically weighs around 118 kDa. It is expressed in various tissues but particularly in endothelial cells and some neuronal tissues. These sites highlight its importance in organs requiring tight regulation of oxygen.
Biological function summary

HIF-2-alpha regulates the expression of genes involved in energy metabolism and angiogenesis. The protein forms a complex by dimerizing with the HIF-1-beta subunit which is necessary for transcriptional activity. Through this complex formation and activity it influences processes such as erythropoiesis and regulates factors like vascular endothelial growth factor (VEGF). Therefore HIF-2-alpha contributes to the adaptation of cells and tissues under hypoxic conditions.

Pathways

HIF-2-alpha engages in the hypoxia signaling pathway playing an essential part by modulating gene expression in response to low oxygen availability. This role impacts other proteins such as HIF-1-alpha sharing overlapping functions but with distinct target genes. Additionally HIF-2-alpha is involved in the mTOR pathway which influences cell growth and metabolism through its interaction with the nutrient-sensing regulatory pathway.

Researchers have linked HIF-2-alpha with conditions like renal cell carcinoma and pulmonary hypertension. The protein's dysregulation can lead to altered expression of angiogenic factors promoting tumor growth and survival. In particular its connection with VEGF exemplifies its role in these pathologies by facilitating aberrant blood vessel formation. Such interactions further highlight the potential of HIF-2-alpha as a therapeutic target in disease modulation.

Target data

Transcription factor involved in the induction of oxygen regulated genes. Heterodimerizes with ARNT; heterodimer binds to core DNA sequence 5'-TACGTG-3' within the hypoxia response element (HRE) of target gene promoters (By similarity). Regulates the vascular endothelial growth factor (VEGF) expression and seems to be implicated in the development of blood vessels and the tubular system of lung. May also play a role in the formation of the endothelium that gives rise to the blood brain barrier. Potent activator of the Tie-2 tyrosine kinase expression. Activation requires recruitment of transcriptional coactivators such as CREBBP and probably EP300. Interaction with redox regulatory protein APEX1 seems to activate CTAD (By similarity).
