  • 产品概述

    Abcam’s PAI1 (SERPINE1) Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of PAI1 concentrations in Human plasma, serum, tissue extracts and cell culture supernatants.

    A PAI1 specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a PAI1 specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate 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 PAI1 captured in plate.

    This assay recognizes both natural and recombinant Human PAI-1.

性能

  • 功能
    Serine protease inhibitor. This inhibitor acts as 'bait' for tissue plasminogen activator, urokinase, protein C and matriptase-3/TMPRSS7. Its rapid interaction with PLAT may function as a major control point in the regulation of fibrinolysis.
  • 组织特异性
    Found in plasma and platelets and in endothelial, hepatoma and fibrosarcoma cells.
  • 疾病相关
    Defects in SERPINE1 are the cause of plasminogen activator inhibitor-1 deficiency (PAI-1D) [MIM:613329]. It is a hematologic disorder characterized by increased bleeding after trauma, injury, or surgery. Affected females have menorrhagia. The bleeding defect is due to increased fibrinolysis of fibrin blood clots due to deficiency of plasminogen activator inhibitor-1, which inhibits tissue and urinary activators of plasminogen.
    Note=High concentrations of SERPINE1 seem to contribute to the development of venous but not arterial occlusions.
  • 序列相似性
    Belongs to the serpin family.
  • 翻译后修饰
    Inactivated by proteolytic attack of the urokinase-type (u-PA) and the tissue-type (TPA), cleaving the 369-Arg-
    -Met-370 bond.
  • 细胞定位
    Secreted.

    can kit be used with mouse samples?
    cross-reactivity of antibodies likely?

    Thank you for contacting us.

    I checked with the lab and they let me know that the homology with mouse is only 2%, thus they do not recommend using it for this species. It will most likely not work.

    Let me know if I can assist you f...

    Thank you for contacting Abcam regarding ab108891.


    Our human kit is specific for human PAI-1 total antigen measurement. It does not cross react with rabbit PAI-1. Unfortunately, we do not have a rabbit specific kit available.
