  • Product overview

    Abcam’s Human uPA (URK) in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of Human uPA in cell culture supernatants, serum and plasma (heparin, EDTA).

    A uPA specific mouse monoclonal antibody has been precoated onto 96-well plates. Standards and test samples are added to the wells and incubated. A biotinylated detection polyclonal antibody from goat specific for uPA is then added followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. TMB is then used to visualize the HRP enzymatic reaction. TMB is catalyzed by HRP 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 Human uPA amount of sample captured in plate.

  • Notes

    Plasminogen activator,urokinase (PLAU, uPA) converts plasminogen to plasmin. Plasmin is involved in processing of amyloid precursor protein and degrades secreted and aggregated amyloid-beta, a hallmark of Alzheimer disease (AD). Urokinase has a molecular mass of about 54 kD and is composed of 2 disulfide-linked chains, A and B, of molecular masses 18 kD and 33 kD, respectively. It localized on 10q24. uPA facilitates cell migration by localizing proteolisys on the cell surface and by inducing intracellular signalling pathways. In human vascular smooth muscle cell (VSMC), uPA stimulates migration via the uPA receptor (uPAR) signalling complex containing TYK2 and phosphatidylinositol 3-kinase (PI3-K).

Customer reviews and Q&As

uPA ELISA - use with citrated plasma

Good Excellent 5/5 (Ease of Use)
We used this kit to quantify urokinase levels in citrated plasma samples. Samples were thawed from -80degrees Celsius and diluted with the sample diluent buffer. The assay was conducted in accordance with the recommended protocol, which was clear and easy to follow throughout.

We encountered no major issues in data acquisition. The attached figure demonstrates the standard curve we obtained and the distribution of sample readings.
