  • 产品名称Anti-eNOS抗体
    参阅全部 eNOS 一抗
  • 描述
    兔多克隆抗体to eNOS
  • 特异性This antibody does not detect human inducible NOS or rat brain nNOS. ab5589 has been successfully used in Western blot and immunohistochemistry (paraffin and frozen) procedures. By Western blot, this antibody detects an ~140 kDa protein representing eNOS from human endothelial cells. Immunohistochemical staining of eNOS in Human vascular endothelial cells with ab5589 results in prominent staining of the epithelial cells.
  • 经测试应用适用于: ICC/IF, IHC-P, IHC-Fr, WBmore details
  • 种属反应性
    与反应: Rabbit, Guinea pig, Cow, Dog, Human, Pig
  • 免疫原

    Synthetic peptide corresponding to Human eNOS aa 1179-1194.
    Sequence:

    SLQERQLRGAVPWAFD

  • 阳性对照
    • IHC: Human endothelial cells. WB:canine cardiac microsomes and rat or human lung lysate.
  • 常规说明

    We have received mixed feedback from customers regarding rat specificity; this is why we are temporarily removing Rat from tested species list and no longer guarantee it. Our laboratory is currently testing new lots so please contact our scientific support team (technical@abcam.com) for more information.

性能

应用

Our Abpromise guarantee covers the use of ab5589 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
ICC/IF Use at an assay dependent concentration. PubMed: 16797727
IHC-P 1/100. Antigen retrieval is not essential but may optimise staining.
IHC-Fr 1/100.
WB 1/1000. Predicted molecular weight: 133 kDa.

By Western blot ab5589 also detects eNOS in canine cardiac microsomes.
5% BSA in TBST is recommended as blocking buffer.

靶标

  • 功能Produces nitric oxide (NO) which is implicated in vascular smooth muscle relaxation through a cGMP-mediated signal transduction pathway. NO mediates vascular endothelial growth factor (VEGF)-induced angiogenesis in coronary vessels and promotes blood clotting through the activation of platelets.
    Isoform eNOS13C: Lacks eNOS activity, dominant-negative form that may down-regulate eNOS activity by forming heterodimers with isoform 1.
  • 组织特异性Platelets, placenta, liver and kidney.
  • 疾病相关Variation in NOS3 seem to be associated with susceptibility to coronary spasm.
  • 序列相似性Belongs to the NOS family.
    Contains 1 FAD-binding FR-type domain.
    Contains 1 flavodoxin-like domain.
  • 翻译后修饰Phosphorylation by AMPK at Ser-1177 in the presence of Ca(2+)-calmodulin (CaM) activates activity. In absence of Ca(2+)-calmodulin, AMPK also phosphorylates Thr-495, resulting in inhibition of activity (By similarity). Phosphorylation of Ser-114 by CDK5 reduces activity.
  • 细胞定位Cell membrane. Membrane, caveola. Cytoplasm, cytoskeleton. Golgi apparatus. Specifically associates with actin cytoskeleton in the G2 phase of the cell cycle and which is favored by interaction with NOSIP and results in a reduced enzymatic activity.

Anti-eNOS antibody 图像

  • IHC image of eNOS staining in human placenta formalin fixed paraffin embedded tissue section*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab5589, 1/100, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

     

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Thanks for your reply.

I have searched our proforma ID's and this number does not come up. I can usually find the order based on when it was placed. Do you know the date the order was placed from Sellex?

Thanks again!

Thanks for sending the email again. Not sure what is going on but the attachement still did not appear on the email. However it seems the customer is very interested in getting a replacement so I'm happy to send one.
