|Protein Name||Endothelial PAS domain-containing protein 1(EPAS-1)|
|Molecular Weight||96718 MW|
|Protein Function||Transcription factor involved in the induction of oxygen regulated genes. Binds to core DNA sequence 5'-[AG]CGTG-3' within the hypoxia response element (HRE) of target gene promoters. 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 seems to require recruitment of transcriptional coactivators such as CREBPB and probably EP300. Interaction with redox regulatory protein APEX seems to activate CTAD (By similarity). .|
|Sequence Similarities||Contains 1 bHLH (basic helix-loop-helix) domain.|
|Subcellular Localization||Nucleus . Nucleus speckle . Colocalizes with HIF3A in the nucleus and speckles. .|

Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 50ug of sample under reducing conditions.
Lane 1: rat thymus tissue lysates,
Lane 2: rat testis tissue lysates,
After Electrophoresis, proteins were transferred to a Nitrocellulose membrane at 150mA for 50-90 minutes. Blocked the membrane with 5% Non-fat Milk/ TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti- HIF2A antigen affinity purified polyclonal antibody (Catalog # PA1129-2) at 0.5 μg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:10000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for HIF2A at approximately 110-120KD. The expected band size for HIF2A is at 96KD.

"We got bands as expected..."

"We sought to see differences in expression of EPAS1 in protein from mouse lung samples. We selected this product because we have used other antibodies from Boster in the past with success. We got bands as expected, but they were not indicative of good conjugation as they were very light. We believe this is because we did not use the recommended Enhanced Chemiluminscent kit with anti-rabbit IgG (EK1002), so we will repeat the experiment with this chemi kit before concluding whether the antibody worked or not. This antibody should work using the chemiluminescent kit recommended...Heed the recommendation of the website and use the chemi kit suggested for high quality visualization."
1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands
3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.
4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
