  • 常规说明

    Under normoxic conditions HIF-1 alpha has a short half-life. It is largely undetectable in cells or tissues grown under normoxic conditions. It is stabilized only at O2 concentrations below 5% and upon stabilization under hypoxic conditions HIF-1 translocates to the nucleus. Therefore we recommend western blots using nuclear extracts and running Hypoxia treated samples as positive control (ab180880). Hypoxia can be induced with treatment using certain agents e.g. CoCl2 or DFO, etc. so proper sample preparation is critical.

靶标

  • 功能

    Functions as a master transcriptional regulator of the adaptive response to hypoxia. Under hypoxic conditions activates the transcription of over 40 genes, including, erythropoietin, glucose transporters, glycolytic enzymes, vascular endothelial growth factor, and other genes whose protein products increase oxygen delivery or facilitate metabolic adaptation to hypoxia. Plays an essential role in embryonic vascularization, tumor angiogenesis and pathophysiology of ischemic disease. Binds to core DNA sequence 5'-[AG]CGTG-3' within the hypoxia response element (HRE) of target gene promoters. Activation requires recruitment of transcriptional coactivators such as CREBPB and EP300. Activity is enhanced by interaction with both, NCOA1 or NCOA2. Interaction with redox regulatory protein APEX seems to activate CTAD and potentiates activation by NCOA1 and CREBBP.
  • 组织特异性

    Expressed in most tissues with highest levels in kidney and heart. Overexpressed in the majority of common human cancers and their metastases, due to the presence of intratumoral hypoxia and as a result of mutations in genes encoding oncoproteins and tumor suppressors.
  • 序列相似性

    Contains 1 basic helix-loop-helix (bHLH) domain.
    Contains 1 PAC (PAS-associated C-terminal) domain.
    Contains 2 PAS (PER-ARNT-SIM) domains.
  • 结构域

    Contains two independent C-terminal transactivation domains, NTAD and CTAD, which function synergistically. Their transcriptional activity is repressed by an intervening inhibitory domain (ID).
  • 翻译后修饰

    In normoxia, is hydroxylated on Pro-402 and Pro-564 in the oxygen-dependent degradation domain (ODD) by EGLN1/PHD1 and EGLN2/PHD2. EGLN3/PHD3 has also been shown to hydroxylate Pro-564. The hydroxylated prolines promote interaction with VHL, initiating rapid ubiquitination and subsequent proteasomal degradation. Deubiquitinated by USP20. Under hypoxia, proline hydroxylation is impaired and ubiquitination is attenuated, resulting in stabilization.
    In normoxia, is hydroxylated on Asn-803 by HIF1AN, thus abrogating interaction with CREBBP and EP300 and preventing transcriptional activation. This hydroxylation is inhibited by the Cu/Zn-chelator, Clioquinol.
    S-nitrosylation of Cys-800 may be responsible for increased recruitment of p300 coactivator necessary for transcriptional activity of HIF-1 complex.
    Requires phosphorylation for DNA-binding.
    Sumoylated; by SUMO1 under hypoxia. Sumoylation is enhanced through interaction with RWDD3. Desumoylation by SENP1 leads to increased HIF1A stability and transriptional activity.
    Ubiquitinated; in normoxia, following hydroxylation and interaction with VHL. Lys-532 appears to be the principal site of ubiquitination. Clioquinol, the Cu/Zn-chelator, inhibits ubiquitination through preventing hydroxylation at Asn-803.
    The iron and 2-oxoglutarate dependent 3-hydroxylation of asparagine is (S) stereospecific within HIF CTAD domains.
  • 细胞定位

    Cytoplasm. Nucleus. Cytoplasmic in normoxia, nuclear translocation in response to hypoxia. Colocalizes with SUMO1 in the nucleus, under hypoxia.

    Answer

    Thank you for your inquiry.

    The placental tissue was a rather unique sample of which we know of no commercial source of and also did not get any more information form the scientist that used it.

    For an IHC positive control we recommend using glioblastoma multiformae.

    I am sorry I could not be of more help and hope this information is nevertheless helpful.

    Asked on Jun 26 2012

    Answer

    Thank you for your call yesterday and for your patience while I have been in touch with the lab regarding the cytospin staining protocol for the images shown on the datasheet.

    We do not have much more information about the protocol, as the cytospin stains were done by an outside lab in 2005 and we did not receive the full protocol. The primary antibody was conjugated to a fluorophore prior to the staining, so no secondary antibody was used. We do not have information about the how the cytospin was prepared.

    I am sorry that we don't have further information regarding this protocol, but if there is anything else that we might be able to do for you please let me know and I'll be happy to help.

    Asked on Jan 20 2012

    Answer

    Thank you very much for your phone call last week.

    HiF1 alpha is a very sensitive target it stabilizes under hypoxic conditions and gets degraded under normoxic conditions. Upon stabilization HIF-1 translocates to the nucleus so we recommend permeabilizing the sections.

    I have attached the protocol that we recommend for HIF1 alpha target staining. Although this protocol is not different than others so may be troubleshooting few steps will helps
    - Antigen retrieval always needs optimizations. 20 minutes is only a suggested antigen retrieval time for Microwave. Less than 20 minutes may leave the antigens under retrieved, leading to weak staining. More than 20 minutes may leave them over-retrieved, leading to nonspecific background staining and also increasing the chances of sections dissociating from the slides. A control experiment is recommended beforehand, where slides of the same tissue section are retrieved for 5, 10, 15, 20, 25 and 30 minutes before being immunohistochemically stained to evaluate optimum antigen retrieval time for the particular antibody being used.
    - We would recommend using citrate buffer as antigen retrieval buffer however for optimizations purpose different buffers can be used e.g. EDTA, Tris EDTA.
    - Tissues sections: the tissue should be fixed immediately after removal; any delays actually degrades the protein.
    - We suggest incubating the section in Normal immune serum or 5% BSA for at least 1-2 hours.
    - Following publications may also help with protocol

    Answer

    Thank you for contacting Abcam. I have had a chance to look through the data for at HIF1 alpha antibody panel (ab10625) that you had spoke of during our conversation. Of the antibodies included in this panel only ab8366 (Anti-HIF1 alpha antibody [ESEE122]) has been tested to work in IHC-Fr. Although the other antibodies may work in with this condition they have not been tested as such and therefore I cannot be confident that this product will meet your needs completely. As such I would recommend using ab8366 for your experiments. Positive controls for this product include glioblastoma multiformae and hypoxia-induced human placenta. I would also like to highly recommend ab1 (Anti-HIF1 alpha antibody [H1alpha67] - ChIP Grade). This product has been tested in IHC-IF on mouse and has been referenced in 33 publications. The Abreviews for this product may also be an excellent resource for your experiments. I've included links to both these antibodies as well as the direct link to the IHC-Fr Abreviews for Ab1 below. ab8366: https://www.abcam.com/hif1-alpha-antibody-esee122-ab8366.html ab1: https://www.abcam.com/HIF1-alpha-antibody-H1alpha67-ChIP-Grade-ab1.html ab1 reviews: https://www.abcam.com/HIF-1-alpha-antibody-H1alpha67-ab1.html&tab=abreviews&intabreviewid=9511 I hope this information helps you.

    Thank you for your enquiry. I apologize that I am unable to answer you in Spanish. Ab8366 has not yet been tested in Western blot, so it may be this antibody is not suitable for that application. You may wish to submit an Abreview of your results from the antibody datasheet. Plese take a look at ab1 and ab2185, both of which were tested in WB and cross-react with rat. I hope this information helps. Please do not hesitate to contact us if you need anything further.

    Question

    I have used antibody ab8366 for western blot and I have a strong band at 60 kDa. I would like to ask if the antibody also recognizes a douple band corresponding to a dimer or is it just 120 kDa the expected band.

    Answer

    120 kDa is the expected band but the 60 kDa band is often seen in both hypoxic and normoxic cells. The same band is often seen when using ab1 as well. We do not know what the 60 kDa band represents at this time. However, using nuclear extracts decreases this background band and increases the HIF-1 alpha signal. ***Abcam does not recommend ab8366 in Western blotting ***

    Question

    In August, we received an anti-body against HIF 1alpha (ab8366). We tested this ab in several differnt western blottings using rat and human endothelial cells (control and 24 hrs hypoxia). None of the blots gave a clear result about the presence of HIF 1alpha. Potocol: boil total protein load and run semi-dry blotting on hybond P or C block with milk powder 5% 1e ab (ab8366) 3 hours 2e anti mouse IgG 45 min. substrate ECL++ kit This results in a laddering pattern of several non-specific bands, without the expected 120 kD band. There is no difference between hypoxia and control samples. Maybe you can give us a few tips for optimising this protocol. Do you know a positive control, wich we can use for this western blot? Futher more, I received an e-mail about a new anti-body against HIF1 alpha, especially for western blotting. Could it be possible that we can test this ab.

    Answer

    Generally speaking, we recommend NB 100-131 (ab8366) for immunohistochemistry work. It has been used for western analyis on human and rat samples (MCF7 and PC12 nuclear extracts). The other antibody of which you speak is ab2185, a polyclonal made to the same fusion protein as ab1 and ab463. It has been tested on the same samples as those mentioned above. ***Update 2006: we do not recommend ab8366 for Western blotting***

    Question

    I have just received your HIF-1 alpha antibody (ref. ab8366)and the protocol suggests to use it at 1:8000. I am just enquiring if this incubation is overnight and whether or not it requires any pre-treatments.

    Answer

    The 1:8,000 dilution was done for 90 minutes at RT by some researchers at the University of Oxford with antigen unmasking. It has also been done at 1:1,000 for 40 hrs at 5C (see review for this product) with pre-treatments (Dako). The dilutions and incubation time seem to vary according to the protocol.
