Applications
Key Applications Immunoblotting (Western Blotting)
Immunoprecipitation
Paraffin Sections
Application NotesImmunoblotting (1:500-1:1000)
Immunoprecipitation (see comments)
Paraffin Sections (1:100, heat pre-treatment required)
Application CommentsAlso reported to immunoprecipitate HIF-1α from nuclear extracts. Has also been reported to stain formalin-fixed, paraffin-embedded tissues; antigen unmasking using heat and citrate buffer, pH 6.0, is recommended prior to detection of HIF-1α in tissue samples.

Regarding immunoblotting to detect HIF-1α:

HIF-1 alpha is the most rapidly degraded protein ever studied. Upon cellular re-oxygenation it is completely degraded in less than 1 min. It is critical to prep only a few plates/dishes/flasks of cells at a time and to immediately get the cells into ice cold buffers and perform the entire protein prep on ice. HIF-1α is largely undetectable in cells or tissues grown under normoxic conditions. It is stabilized only at O2 concentrations below 5% or with treatment using certain agents (CoCl2, DFO, etc.) so proper sample preparation is critical. Upon stabilization HIF-1α translocates to the nucleus. The cleanest immunoblots are always done using nuclear extracts. It is possible to detect HIF-1α in whole cell extracts, but they tend to be much dirtier and the staining is much weaker. Finally, we recommend that positive and negative controls always be run side by side so that it is possible to discern which band is upregulated in the hypoxic sample. Unprocessed HIF-1α is ~95 kDa while the fully post-translationally modified form is ~116 kDa or larger. Additionally, HIF-1α may form a heterodimer with HIF-1β (Duan, et al.).
Depending on the sample, treatment methods, etc. HIF-1α may appear as a single band or as a doublet.

Variables associated with assay conditions will dictate the optimal dilution.

DescriptionProtein G purified mouse monoclonal antibody. Recognizes several proteins of ~120 kDa representing multiple post-translationally modified forms of HIF-1α.
BackgroundHIF-1 is a nuclear protein that activates gene transcription in response to reduced cellular O2 concentration. HIF-1 activates the transcription of EPO, VEGF, iNOS, heme oxygenase 1, and several other critical intracellular responses to hypoxia. HIF-1 is a heterodimer composed of 2 basic-helix-loop-helix PAS subunits, HIF-1α and HIF-1β. Both subunits are induced by hypoxia and rapidly decay upon return to normoxia. Recent research suggests the ability to regulate hypoxia-inducible factors may be related to tumor-related angiogenesis in certain cancers.
