Description

• Store vial at -20°C prior to opening
• Aliquot contents and freeze at -20°C or below for extended storage
• Avoid cycles of freezing and thawing
• Centrifuge product if not completely clear after standing at room temperature
• This product is stable for several weeks at 4°C as an undiluted liquid
• Dilute only prior to immediate use
• This antibody is directed against human HIF-1a hydroxyP564 and is specific for the hydroxylated form of the protein
• Minimal reactivity occurs with the non-hydroxylated form of the protein
• A BLAST analysis was used to suggest cross-reactivity with HIF-1a from human, monkey, mouse, rat, dog, bovine and Xenopus sources based on a 100% homology with the immunizing sequence
• Reactivity against homologues from other sources is not known
• HIF1-alpha (HIF1A) is a subunit of HIF1, which is a transcription factor found in mammalian cells cultured under reduced oxygen tension
• HIF-1 is a heterodimer consisting of an alpha and beta subunit, both belonging to the basic-helix-loop-helix Per-aryl hydrocarbon receptor nuclear translocator-Sim (PAS) family of transcription factors
• HIF1 functions as a transcriptional regulator of the adaptive response to hypoxia
• Under hypoxic conditions, HIF-1 activates the transcription of over 40 genes, including erythropoietin, glucose transporters, glycolytic enzymes, vascular endothelial growth factor, HILPDA, and other genes whose protein products increase oxygen delivery or facilitate metabolic adaptation to hypoxia
• HIF1-alpha regulates hypoxia-mediated apoptosis, cell proliferation and tumor angiogenesis
• Hypoxia which induces p53 protein accumulation, directly interacts with HIF1-alpha and reduces hypoxia-induced expression of HIF1-alpha by promoting MDM2-mediated ubiquitination and proteasomal degradation under hypoxic conditions
• Recent studies suggest that induction of NOX4 by HIF1-alpha contributes to maintain ROS levels after hypoxia and hypoxia-induced proliferation
• In humans, it is located on the q arm of chromosome 14
• The C-terminal of HIF1A binds to p300
• p300/CBP-HIF complexes participate in the induction of hypoxia-responsive genes, including VEGF
• 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.
