Product details:
Abcam's Urokinase type Plasminogen Activator Human
in vitro
ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Urokinase type Plasminogen Activator (uPA) in plasma, serum, urine, milk, cell culture supernatants and tissue extracts.
A Urokinase type Plasminogen Activator specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a Urokinase type Plasminogen Activator specific biotinylated detection antibody is added and then followed by washing with wash buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize 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 amount of Urokinase type Plasminogen Activator captured in plate.
The entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.

Urokinase also known as urokinase-type plasminogen activator (uPA) is a serine protease with a molecular mass of approximately 54 kDa. It is expressed in various tissues including the kidneys liver and blood vessels. Urokinase initially forms as pro-urokinase an inactive precursor that can convert into the active enzyme. Researchers often use assays like the direct assay to measure urokinase activity due to its role in breaking down fibrin and modulating cell adhesion and migration.
Biological function summary
Something particularly interesting about urokinase is its role in converting plasminogen to plasmin a critical enzyme in the process of fibrinolysis. Moreover it is part of a larger enzymatic complex involving the urokinase receptor (uPAR) which localizes plasminogen activation to cell surfaces. This complex mediates extracellular matrix degradation aiding in important cellular processes like tissue remodeling and wound healing.
Pathways
Urokinase plays a critical role in the fibrinolytic pathway which involves the breakdown of blood clots. It also interacts with the extracellular matrix pathway by activating plasminogen which can degrade matrix components. In these pathways urokinase closely interacts with proteins such as plasmin and its inhibitor plasminogen activator inhibitor-1 (PAI-1) which regulate the activity and localization of proteolytic events.
Urokinase is strongly linked to conditions such as deep vein thrombosis and cancer metastasis. Its overexpression or dysregulation often leads to excessive tissue degradation influencing metastasis progression. Urokinase is connected to the urokinase receptor (uPAR) in cancer facilitating cancer cell invasion and migration. Understanding its behavior in these contexts is critical for developing therapeutic strategies and targeting treatments against these diseases.
