Application(s)WB
Antibody HostRabbit
Antibody TypePolyclonal
SpecificityDetects HIF2A by Western Blotting in tissue homogenates. Rat. Expected to react with mouse HIF2A due to immunogen sequence homology.
Species ReactivityHuman, Mouse (Predicted), Rat
Immunogen DescriptionA synthetic peptide (HALDSENMTKSHQNLCTKG) corresponding to a peptide sequence in the middle region (282-301) from human Hypoxia-inducible factor-2 alpha. This sequence is identical to rat and mouse HIF2A.
ConjugateUnconjugated
Purity DescriptionAffinity purified on antigen column
Application DetailsWestern Blotting (WB). A concentration of 0.1-0.5 µg/mL is recommended for WB. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Reconstitution InstructionsSpin vial briefly before opening. Reconstitute in 100 µL sterile-filtered, ultrapure water to achieve an antibody concentration of 1 mg/mL. Centrifuge to remove any insoluble material.
Storage InstructionsStore lyophilized antibody at 2-8°C. After reconstitution, aliquot and store at -20°C for a higher stability. Avoid freeze-thaw cycles.
Batch NumberPlease see item label.
Expiration Date12 months after date of receipt (unopened vial).

Scientific BackgroundTranscription 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 CREBBP and probably EP300. Interaction with redox regulatory protein APEX seems to activate CTAD (Reference: uniprot.org).
Western blot analysis of HIF2A expression in rodent samples using R-1786-100. Lane 1: rat thymus tissue lysate (50 µg), Lane 2: rat testis tissue lysate (50 µg). The expected band size for HIF2A is 96 kD, but might run slower on SDS-PAGE due to post-translational modifications. Method: SDS-PAGE: denaturing and reducing, 5-20% gel; Membrane: nitrocellulose; Blocking: 5% skim milk in TBST, 1.5 hours at RT; Primary antibody: overnight at 4°C (0.5 µg/mL); Secondary antibody: anti-rabbit-HRP (1/10000), 1.5 hours at RT; Detection: Chemiluminiscence.
