HIF1 (hypoxia-inducible factor 1), a heterodimeric transcription factor complex central to cellular response to hypoxia, consists of two subunits (HIF-1 alpha and HIF-1 beta) which are basic helix-loop-helix proteins of the PAS (Per, ARNT, Sim) family. Expression of HIF-1 alpha protein is regulated by cellular oxygen level alterations as well as in oxygen-independent manner via different cytokines (through the PI3K-AKT-mTOR pathway), growth factors, oncogenic activation, or loss of tumor suppressor function etc. In normoxic cells, HIF-1 alpha is proline hydroxylated leading to a conformational change that promotes its binding to the VHL (von Hippel Lindau) protein E3 ligase complex; ubiquitination and followed by rapid proteasomal degradation. Hypoxia as well as chemical hydroxylase inhibitors (desferrioxamine, cobalt etc.) inhibit HIF-1 alpha degradation and lead to its accumulation in the cells, whereas, contrastingly, HIF-1 beta/ARNT (AhR nuclear translocator) remains stable under both conditions. Besides their critical role in hypoxic response, HIF1s regulates the transcription of genes responsible for angiogenesis, erythropoiesis/iron-metabolism, glucose metabolism, cell proliferation/survival, adipogenesis, carotid body formation, B lymphocyte development and immune reactions.

FAQs for HIF-1 alpha Antibody (NBP1-47178). (Showing 1 - 4 of 4 FAQ).

  1. 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.
  2. 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).
  3. 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.
  4. 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.
