|Product name||Rat Urokinase (UK) ELISA Kit|
|Applications notes||This Rat Urokinase (UK) ELISA Kit employs a two-site sandwich ELISA to quantitate UK in samples. An antibody specific for UK has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyUK present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for UK is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of UK bound in the initial step. The color development is stopped and the intensity of the color is measured.|

|Usage notes||• Do not mix components from different kit lots or use reagents beyond the kit expiration date.
• Allow all reagents to warm to room temperature for at least 30 minutes before opening.
• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.
• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
• It is recommended that all samples and standards be assayed in duplicate or triplicate.
|Storage instructions||The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.|

|Background||Urokinase-type plasminogen activator is a serine protease involved in degradation of the extracellular matrix and possibly tumor cell migration and proliferation. The protein encoded by this gene converts plasminogen to plasmin by specific cleavage of an Arg-Val bond in plasminogen. This gene's proprotein is cleaved at a Lys-Ile bond by plasmin to form a two-chain derivative in which a single disulfide bond connects the amino-terminal A-chain to the catalytically active, carboxy-terminal B-chain. This two-chain derivative is also called HMW-uPA (high molecular weight uPA). HMW-uPA can be further processed into LMW-uPA (low molecular weight uPA) by cleavage of chain A into a short chain A (A1) and an amino-terminal fragment. LMW-uPA is proteolytically active but does not bind to the uPA receptor.|
