The hypoxia-inducible transcription factor 1 alpha (HIF-1 alpha ) is the regulated member of the transcription factor heterodimer HIF-1. HIF-1 binds to hypoxia-response elements (HREs) in the promoters of many genes involved in adapting to an environment of insufficient oxygen or hypoxia. Hypoxic tissue environments occur in vascular and pulmonary diseases as well as cancer, which illustrates the broad impact of gene regulation by HIF-1 alpha.

FAQs for HIF-1 alpha Antibody (MAB1536). (Showing 1 - 4 of 4 FAQs).

  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.
