Optimized DNA sequence encoding peptidase domain of Human Hypoxia inducible factor 1 alpha (ARG575 - ASN826) including an N-terminal His tag was expressed in E.Coli.
Recombinant human HIF-1α is a protein consisting of 260 amino acid residue subunits, migrates as an approximately 35kDa protein on reduced SDS-PAGE.
>95%, as determined by SDS-PAGE and HPLC
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Recombinant Human Hypoxia inducible factor 1 is lyophilized from 0.2 μm filtered PBS solution, pH7.2 , 5% Trehalose.
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Recombinant HIF-1α can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.

Hypoxia inducible factor 1
A key factor involved in the
cell response to reduced
oxygen levels is hypoxia-
factor . HIF is a
heterodimer that consists of
a hypoxic response α subunit
and the constitutively
expressed subunit HIF-1β. In
the presence of oxygen, HIF-
α is bound to the von
suppressor protein. This
interaction causes HIF-α to
become ubiquitylated and
targeted to the proteasome,
where it is degraded. Under
hypoxic conditions, HIF-α
becomes stable and binds
HIF-1β to form the active
HIF transcription factor,
which binds to hypoxia-
response elements activating
the expression of numerous
Stabilization of HIF-α in
cancer cells is believed to
be one of the most important
mechanisms that promotes
metastasis and, thereby,
the role of hypoxia-inducible factor-1α and vascular endothelial growth factor in late-phase preconditioning with xenon, isoflurane and levosimendan in rat cardiomyocytes
