General notes
Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.
Please check that this product meets your needs before purchasing.

Western blot - Anti-HIF-2-alpha antibody (ab199) Image from PLoS One. 2012; 7(1): e29876. Fig3A, doi: 10.1371/journal.pone.0029876 Reproduced under the Creative Commons license http://creativecommons.org/licenses/by/4.0/HIF-2α levels in HIF-2α−/− and WT mouse kidneys.
HIF-2α−/− mice or their wild-type littermates were exposed to left ureteral obstruction (UO), which continued for 24 hours, and then was released. 2 days after release of UO or at the corresponding time point in the non-UO sham-operated mice, the left kidneys were harvested and subjected to immunoblot analyses of HIF-2α and co-detection of TBP as a loading control
Nuclear extracts were isolated from harvested whole kidneys using NE-PER Nuclear and Cytoplasmic Extraction Reagents supplemented with Complete Protease Inhibitor Cocktail Tablets. Nuclear protein fractions were electrophoresed on 10% SDS-PAGE under reducing conditions and transferred to a nitrocellulose membrane. Membranes were blocked with LI-COR blocking buffer (LI-COR Biosciences, Lincoln, NE). Membranes were then incubated with the same blocking solution containing rabbit polyclonal primary antibodies against HIF-2α (1:500, ab199). After washing, membranes were incubated at room temperature for 1 h in TBS/0.05% Tween 20 buffer with the IRDye800 secondary antibodies (1:10000) and then washed again in TBS/0.05% Tween 20 for 3 times. The blot was visualized using an Odyssey infrared imaging system. All values were normalized to a loading control TATA binding protein (TBP, 1:2000, ab818, Abcam) and expressed as fold increase relative to control.

Immunocytochemistry/ Immunofluorescence - Anti-HIF-2-alpha antibody (ab199)ICC/IF image of ab199 stained HepG2 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab199, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Lane 2 : 20ug of whole cell lysate from PC12 cells exposed to hypoxic conditions (12 hours at 3% oxygen).
Lane 3 : 20ug of whole cell lysate from PC12 cells exposed to hypoxic conditions (12 hours at 3% oxygen) and incubated with antisense HIF2 alpha oligonucleotides 72 hours prior to treatment.
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 100 kDa
Observed band size: 96 kDa why is the actual band size different from the predicted?
The blots were probed with anti-alpha tubulin as a loading control.
