Hypoxia-inducible factor-1 (HIF1) is a transcription factor found in mammalian cells cultured under reduced oxygen tension that plays an essential role in cellular and systemic homeostatic responses to hypoxia. HIF1 is a heterodimer composed of an alpha subunit and a beta subunit. The beta subunit has been identified as the aryl hydrocarbon receptor nuclear translocator (ARNT). This gene encodes the alpha subunit of HIF-1. Overexpression of a natural antisense transcript (aHIF) of this gene has been shown to be associated with nonpapillary renal carcinomas. Two alternative transcripts encoding different isoforms have been identified. [provided by RefSeq]

FAQs for HIF-1 alpha Recombinant Protein (H00003091-P01). (Showing 1 - 5 of 5 FAQs).
Why is there a difference between the theoretical MW for HIF1A and the observed MW for HIF-1 alpha?
HIF1A, like many other proteins, has post-translational modifications. Depending on the size, amount and nature of the post-translational modifications, it can cause subtle to very large changes in molecular weight.
Which antibody(ies) do you recommend for the detection of HIF-1a by immunohistochemistry in the sections of paraffin-embedded mouse liver samples? I would appreciate if you can give me several choices and rank them in the order of performance. My goal is to distinguish HIF upregulation by prolyl hydroxylase inhibitor in different liver cells.
All of our antibodies are of high quality and are well tested/validated in species/applications we list on the datasheet. However, as desired by you, I am suggesting you four HIF-1 alpha antibodies based upon customer reviews, as well as the number of peer reviewed publications in which these products has been cited by researchers from reputed institutes. (1) HIF-1 alpha Antibody (H1alpha67) (cat# NB100-105) (cited in at least 218 peer reviewed publications) (2) HIF-1 alpha Antibody (cat# NB100-479) (cited in at least 51 peer reviewed publications) (3) HIF-1 alpha Antibody (H1alpha67) (cat# NB100-123 ) (cited in at least 38 peer reviewed publications) (4) HIF-1 alpha Antibody (cat# NB100-449 ) (cited in at least 31 peer reviewed publications).
I would like to know, does it exist path for detection HIF 1 in the venous blood before and after revascularization of the leg?
We are not entirely sure if HIF-1 alpha will be present in the leg after revascularization. It may be present but you may want to search the literature to see if this has been looked at before. If not, then this would certainly be an experiment worth doing.
What is the molecular weight (kDa) of protein HIF 1 alpha in western blot?
The theoretical molecular weight of HIF 1-alpha is ~93kDa, however, you will likely see a band between 100-120kDa due to phosphorylation.
What's the concentration of H00003091-P01 (HIF-1 alpha Recombinant Protein) lot D1221?
This particular product is manufactured by a Taiwanese company called Abnova (we distribute their products in addition to selling our own). The concentration of H00003091-P01 lot D1221 is 0.21 mg/ml.

HIF-1 Alpha: Infographic Encoded by the HIF1A gene, HIF-1 alpha has a critical role in cellular response to hypoxia. In hypoxic conditions, HIF-1 alpha activates the transcription of several genes to facilitate metabolic reaction for lack of oxygen. In normoxic conditions, HI... Read full blog post.
Controlling the HIF-1 Switch Hypoxia-inducible factor-1 is a major transcription factor composed of two subunits: HIF-1alpha and HIF-1 beta. Under normoxic conditions, HIF-1 alpha is targeted to proteosomal degradation via ubiquitination. On the other hand during hypoxic conditio... Read full blog post.
