  • 製品の概要

    Abcam’s Factor XI Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Factor XI levels in plasma, serum, and cell culture supernatants.

    A Factor XI specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a Factor XI specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Complex is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of Factor XI captured in plate.

製品の特性

  • 機能
    Factor XI triggers the middle phase of the intrinsic pathway of blood coagulation by activating factor IX.
  • 組織特異性
    Isoform 2 is produced by platelets and megakaryocytes but absent from other blood cells.
  • 関連疾患
    Factor XI deficiency (FA11D) [MIM:612416]: A hemorrhagic disease characterized by reduced levels and activity of factor XI resulting in moderate bleeding symptoms, usually occurring after trauma or surgery. Patients usually do not present spontaneous bleeding but women can present with menorrhagia. Hemorrhages are usually moderate. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • 配列類似性
    Belongs to the peptidase S1 family. Plasma kallikrein subfamily.
    Contains 4 apple domains.
    Contains 1 peptidase S1 domain.
  • 翻訳後修飾
    Activated by factor XIIa (or XII), which cleaves each polypeptide after Arg-387 into the light chain, which contains the active site, and the heavy chain, which associates with high molecular weight (HMW) kininogen.
