靶标

  • 功能

    Important in the maintenance of hemostasis, it promotes adhesion of platelets to the sites of vascular injury by forming a molecular bridge between sub-endothelial collagen matrix and platelet-surface receptor complex GPIb-IX-V. Also acts as a chaperone for coagulation factor VIII, delivering it to the site of injury, stabilizing its heterodimeric structure and protecting it from premature clearance from plasma.

  • 组织特异性

    Plasma.

  • 疾病相关

    Defects in VWF are the cause of von Willebrand disease (VWD) [MIM:277480]. VWD defines a group of hemorrhagic disorders in which the von Willebrand factor is either quantitatively or qualitatively abnormal resulting in altered platelet function. Symptoms vary depending on severity and disease type but may include prolonged bleeding time, deficiency of factor VIII and impaired platelet adhesion. Type I von Willebrand disease is the most common form and is characterized by partial quantitative plasmatic deficiency of an otherwise structurally and functionally normal Willebrand factor; type II is associated with a qualitative deficiency and functional anomalies of the Willebrand factor; type III is the most severe form and is characterized by total or near-total absence of Willebrand factor in the plasma and cellular compartments, also leading to a profound deficiency of plasmatic factor VIII.

  • 序列相似性

    Contains 1 CTCK (C-terminal cystine knot-like) domain.
    Contains 4 TIL (trypsin inhibitory-like) domains.
    Contains 3 VWFA domains.
    Contains 3 VWFC domains.
    Contains 4 VWFD domains.

  • 结构域

    The von Willebrand antigen 2 is required for multimerization of vWF and for its targeting to storage granules.

  • 翻译后修饰

    All cysteine residues are involved in intrachain or interchain disulfide bonds.
    N- and O-glycosylated.

  • 细胞定位

    Secreted. Secreted > extracellular space > extracellular matrix. Localized to storage granules.

    Question

    I've used your mouse monoclonal von willebrand Factor antibody (ab778)for IHC in my experiments. The data will be published. The edditors asked us to show the specificity of this antibody. Your data sheet showed 3 references. I checked them and found no one exactely used this antibody for IHC. Could you tell me where the image (a good staining)in the data sheet was cited from? Do you have the antigen for this antibody? Or could you tell me what company has this antigen? I will buy the antigen of this antobody to run the preabsorption experiment.

    Answer

    Thank you for contacting us.

    The lab sent me the following information regarding your question:

    Based on the data Factor VIII reacts specifically with the endothelial cells of normal, reactive, and neoplastic blood and lymphatic vessels and shows finely granular cytoplasmic staining. It also reacts with endocardium, platelets, and megakaryocytes.

    Please let me know if this information is sufficient.

    Answer

    Thank you for contacting us.

    I have emailed the lab to check regarding the specificity testing, and I'll let you know what I find out.
    The IHC image on the datasheet is from the lab.

    The immunogen used to raise the antibody was Von Willebrand Factor isolated from human plasma. We carry vWF protein (ab88533 and ab88555) that can be used for blocking, although we have not tried that application with these 2 proteins.

    https://www.abcam.com/Von-Willebrand-Factor-protein-Human-ab88555.html

    You can use our testing discount program to try either protein in a blocking experiment.

    For UNTESTED species and/or applications, we have established a testing discount program. Here is a brief description of how it works:

    The testing discount program is for customers who like to use an antibody/protein/kit on an untested species/application. You would purchase the antibody/protein/kit at full price, test it and submit an Abreview with your data (positive or negative). On your next order you will receive a discount for ONE antibody/protein at the full price (100%) of the antibody/protein you have tested, or a full price discount for the amount paid for the kit. The terms and conditions applicable to this offer can be found here: https://www.abcam.com/collaborationdiscount.
    This programapplies to ELISA kits and other kits we offer.

    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
