HIF1a, the major regulator of the cellular responses to hypoxia, consists of an oxygen-sensitive subunit, HIF1 alpha (HIF1A), and an oxygen-insensitive subunit, HIF1 beta (arylhydrocarbon receptor nuclear transporter [ARNT]). Under normal oxygen conditions, HIF1a is continuously produced and destroyed, in a process involving hydroxylation, interaction with von Hippel-Lindau (VHL) protein, polyubiquitylation and subsequent proteasomal degradation. Under hypoxic conditions, hydroxylation is impaired and HIF1a is stabilized. HIF1a localizes in cytoplasm in normoxia, but it can translocate into nuclear in response to hypoxia. The calculated molecular weight of HIF1a is 93 kDa, but the modified protein HIF1a is about 110-120kDa (PMID: 11698256, .PMID: 7539918). .

The image uploaded refers to a hypoxic condition O2<1%. The antibody signal was aspecific and generated aspecific binding in the middle of the organoid.

Unfortunately much background an many unspecific bands in lysates of human chondrocytes and BV2 microclia cells (less unspecific bands in rat chondrocytes).

Separated on a 7.5% SDS PAGE gel, transferred to nitrocellulose membrane. Block with 5% dry milk/PBST at room temperature for one hour. 1:1000 dilution of the primary antibody in blocking solution. Incubated overnight at 4 degrees C on a rocker platform. Secondary antibody 1:1000 secondary (anti rabbit HRP) incubation for two hours at room temperature. Visualization with the Opti-4CN chromogenic substrate kit (BioRad).
