| CatalogCode: | | NB100-479SS |
| ProductName: | | HIF-1 alpha Antibody |
| Product Description: | | Rabbit Polyclonal anti-HIF-1 alpha |
| Clonality: | | Polyclonal |
| Immunogen: | | A fusion protein including residues 530-825 of the mouse HIF-1 alpha protein. |
| Specificity: | | This antibody is specific for mouse HIF-1 alpha. |
| CrossReactivity: | | This antibody reacts against human, mouse, rat, and primate protein. Other species have not yet been determined. |
| Packaging: | | 0.025 ml Immunogen affinity purified Rabbit antisera. |
| Uses: | | This antibody has been tested in Western blot, recognizing a band in hypoxic samples at ~115 kDa. It has only been tested against mouse, rat, human and primate protein. Rat retina and brain cortex have been tested. Rat brain cortex is a bit dirty but this antibody does detect upregulation of HIF-1 alpha in hypoxic samples. This antibody is not recommended for immunoprecipitation. |
| Background: | | 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. HIF-1 is a nuclear protein involved in mammalian oxygen homeostasis. This occurs as a posttranslational modification by prolyl hydroxylation. HIF-1 is a heterodimer composed of HIF-1 alpha and HIF-1 beta subunits. Both subunits are constantly translated. However, under normoxic conditions, human HIF-1 alpha is hydroxylated at Pro402 or Pro564 by a set of HIF prolyl hydroxylases, is polyubiquinated, and eventually degraded in proteosomes. Under hypoxic conditions, the lack of hydroxylation prevents HIF degradation and increases transcriptional activity. Therefore, the concentration of HIF-1 alpha increases in the cell. In contrast, HIF-1 beta remains stable under either condition. HIF hydroxylases provide insight into hypoxic cell responses, which may be used to help isolate therapeutic targets. |

| NotesMain: | | You may use COS-7 treated and untreated nuclear extracts for your positive and negative controls for hypoxic upregulation. * The mobility of HIF-1 alpha induced by desferrioxamine or cobalt chloride treatment differs from the mobility of the hypoxia-induced protein. The reason is not known. |
