    Abcam’s Plasminogen (PLG) Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Plasminogen concentrations in Human plasma, serum, urine, saliva, milk, tissue samples, cerebrospinal fluid and cell culture supernatants.

    A Plasminogen specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a Plasminogen 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 Plasminogen captured in plate.

  • 機能Plasmin dissolves the fibrin of blood clots and acts as a proteolytic factor in a variety of other processes including embryonic development, tissue remodeling, tumor invasion, and inflammation. In ovulation, weakens the walls of the Graafian follicle. It activates the urokinase-type plasminogen activator, collagenases and several complement zymogens, such as C1 and C5. Cleavage of fibronectin and laminin leads to cell detachment and apoptosis. Also cleaves fibrin, thrombospondin and von Willebrand factor. Its role in tissue remodeling and tumor invasion may be modulated by CSPG4. Binds to cells.
    Angiostatin is an angiogenesis inhibitor that blocks neovascularization and growth of experimental primary and metastatic tumors in vivo.
  • 組織特異性Present in plasma and many other extracellular fluids. It is synthesized in the liver.
  • 関連疾患Defects in PLG are the cause of plasminogen deficiency (PLGD) [MIM:217090]. PLGD is characterized by decreased serum plasminogen activity. Two forms of the disorder are distinguished: type 1 deficiency is additionally characterized by decreased plasminogen antigen levels and clinical symptoms, whereas type 2 deficiency, also known as dysplasminogenemia, is characterized by normal, or slightly reduced antigen levels, and absence of clinical manifestations. Plasminogen deficiency type 1 results in markedly impaired extracellular fibrinolysis and chronic mucosal pseudomembranous lesions due to subepithelial fibrin deposition and inflammation. The most common clinical manifestation of type 1 deficiency is ligneous conjunctivitis in which pseudomembranes formation on the palpebral surfaces of the eye progresses to white, yellow-white, or red thick masses with a wood-like consistency that replace the normal mucosa.
  • 配列類似性Belongs to the peptidase S1 family. Plasminogen subfamily.
    Contains 5 kringle domains.
    Contains 1 PAN domain.
    Contains 1 peptidase S1 domain.
  • ドメインKringle domains mediate interaction with CSPG4.
  • 翻訳後修飾N-linked glycan contains N-acetyllactosamine and sialic acid. O-linked glycans consist of Gal-GalNAc disaccharide modified with up to 2 sialic acid residues (microheterogeneity).
    In the presence of the inhibitor, the activation involves only cleavage after Arg-580, yielding two chains held together by two disulfide bonds. In the absence of the inhibitor, the activation involves additionally the removal of the activation peptide.
  • 細胞内局在Secreted. Locates to the cell surface where it is proteolytically cleaved to produce the active plasmin. Interaction with HRG tethers it to the cell surface.

Review of Abcam Plasminogen Human ELISA Kit:

The Plasminogen ELISA, using the Abcam human ELISA kit Ab108893, Lot GR270028-6, was performed by an experienced laboratory technician at an accredited university. The goal of the experiment was to determine the cross-reactivity for rhesus macaque in both EDTA prepared plasma and in serum samples.

Overall, the kit, like other Abcam ELISA kits, was easy to follow and simple to use.

Our experiment consisted of using EDTA-prepared plasma samples and serum samples from N=3 M. mulatta. Samples were stored prior to thaw at -80 degrees Celsius. Samples were diluted serially in a range from 1:5000 to 1:80000 in the given diluent in duplicate. The rest of the assay was performed per protocol’s instructions.

At 1:80000, all samples were below the range of detection. At 1:40000, most samples were below the range of detection. At 1:20000 a few samples were below the range of detection, but most were in range. 1:5000 and 1:10000 were both in the range of detection for all sample types *subtracted ODs in the 0.6 and 0.5 range respectively). The data presented are the extrapolated values.

Overall, the kit is cross-reactive with both Rhesus plasma and Serum, however we were unable to confirm linearity of detection and value ranges are less than expected.

Used the kit for the first time and diluted my plasma samples (citrate plasma) 1:20000 as suggested in the manual.
This dilution was right for almost all of my samples.
Followed the kit's instructions and had my results in about 4h.

Will use it again and can highly recommend it.

The kit will recognize the plasmin A chain. This information is according to the uniprot information given below:

Plasmin heavy chain A: aa 20-580
Plasmin heavy chain A, short form: aa 98-580
Plasmin light chain B: 581-810
