HIF-1α monoclonal antibody (Hα111a)

Hypoxia inducible factor-1 (HIF-1) is a transcriptional complex which regulates systemic, local and intracellular homeostatic responses elicited by hypoxia. HIF-1 is a heterodimer of HIF-1alpha and HIF-1beta. HIF-1beta is constitutively expressed and serves as a dimerization partner for several other transcription factors, while HIF-1alpha and the closely related HIF-2 are unique to HIF-1 and their expression is tightly regulated by cellular oxygen concentration. HIF-1 regulates a diverse group of genes, including erythropoietin, VEGF, glucose transporters, heme oxygenase, and NOS.
