Alternate Names for HIF-1 alpha Antibody (H1alpha67) [HRP]
Hypoxia contributes significantly to the pathophysiology of major categories of human disease, including myocardial and cerebral ischemia, cancer, pulmonary hypertension, congenital heart disease and chronic obstructive pulmonary disease. HIF-1 is a nuclear protein involved in mammalian oxygen homeostasis. This occurs as a posttranslational modification by prolyl hydroxylation. HIF-1 is a heterodimer composed of HIF-1 alpha and HIF-1 beta subunits. Both subunits are constantly translated. However, under normoxic conditions, human HIF-1 alpha is hydroxylated at Pro402 or Pro564 by a set of HIF prolyl hydroxylases, is polyubiquinated, and eventually degraded in proteosomes. Under hypoxic conditions, the lack of hydroxylation prevents HIF degradation and increases transcriptional activity. Therefore, the concentration of HIF-1 alpha increases in the cell. In contrast, HIF-1 beta remains stable under either condition. HIF hydroxylases provide insight into hypoxic cell responses, which may be used to help isolate therapeutic targets.

FAQs for HIF-1 alpha Antibody (NB100-105H). (Showing 1 - 4 of 4 FAQ).
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.
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.

HIF Antibodies: Beyond HIF-1 alpha The hypoxia inducible factors are a family of heterodimeric transcription factors which are activated in response to lowered oxygen levels, or hypoxia. Although it may seem that HIF-1 alpha receives all the attention, other HIF antibodies, such as the... Read full blog post.
Hypoxia-Inducible Factors and Homeostasis Hypoxia-Inducible Factor-1 (HIF-1) is a highly conserved heterodimeric transcription factor. Novus' antibody catalogue contains an extensive range of both HIF-1 alpha and HIF-1 beta, useful for hypoxia, angiogenesis, cancer and many other areas of res... Read full blog post.
