The Human Acylation Stimulating Protein (ASP) ELISA Kit is a sandwich enzyme immunoassay for the in vitro quantitative measurement of ASP in human serum, plasma and other biological fluids.
Catalog #023120
Detection Range0.156 – 10ng/ml
Sensitivity< 0.073ng/ml
PrecisionIntra-Assay: CV<10%
Inter-Assay: CV<12%
Test PrincipleThe microtiter plate provided in this kit has been pre-coated with an antibody specific to ASP. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to ASP. 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 ASP, 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 ASP in the sample is then determined by comparing the O.D. of the sample to the standard curve.
