The Urokinase Plasminogen Activator (uPA) BioAssay™ ELISA Kit (Mouse) ELISA kit is a sandwich enzyme immunoassay for the in vitro quantitative measurement of uPA in mouse serum, plasma and other biological fluids.
Detection Range
0.156-10ng/ml
Precision
Intra-Assay: CV<10% Inter-Assay: CV<12%
Test Principle
The microtiter plate provided in this kit has been pre-coated with an antibody specific to uPA. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to uPA. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain uPA, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulfuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of uPA in the sample is then determined by comparing the O.D. of the sample to the standard curve.
