Mouse anti Human HIF1 alpha antibody, clone Halpha111a recognizes human Hypoxia-inducible factor 1-alpha otherwise known as HIF1 alpha (HIF1A) or ARNT interacting protein, a widely expressed bHLH-PAS transcription factor, which acts as a critical regulatory protein in the host response to hypoxia (Kubis et al. 2005).

HIF1A and HIF1B, also known as ARNT form the highly-conserved heterodimeric HIF-1 transcriptional complex (Carmeliet et al. 1998). During hypoxic conditions, HIF1A accumulates in the nucleus and activates the transcription of many genes encoding proteins involved in the production of oxygen delivery and metabolic adaptation, such as those for vascular endothelial growth factor (VEGFA) . Under normal oxygen conditions, HIF1A is targeted by hypoxia inducible factor prolyl-hydroxylases, followed by rapid protease degradation, which is inhibited during hypoxia (Hirsilä et al. 2003). Overexpression of HIF1A occurs in many common human cancers, including pancreatic, bladder and renal carcinomas (Shibaji et al. 2003).

Mouse anti Human HIF1α, clone Halpha111a has been successfully used for the identifcation of HIF1α in human samples by both immunohistochemistry and western blotting.

Storage Information

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.
