Product Description

The Nitric Oxide Synthase 3, Endothelial (NOS3) BioAssay(TM) ELISA Kit (Human) is a sandwich enzyme immunoassay for the in vitro quantitative measurement of NOS3 in human serum, plasma, tissue homogenates, cell lysates, cell culture supernatants and other biological fluids. Detection Range: 0.156 - 10ng/ml Sensitivity: <0.057ng/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 NOS3. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to NOS3. 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 NOS3, 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 NOS3 in the sample is then determined by comparing the O.D. of the sample to the standard curve. Kit Components: *027167A: Microtiter Plate, 1x96 wells.

Store all the other components at 4C. Unused kit is stable for 6 months. Once kit components are opened, it is highly recommended to use remaining reagents within 1 month provided this is within the expiration date of the kit. For maximum recovery of product, centrifuge the original vials after thawing and prior to removing the cap. Assay Summary: 1. Prepare all reagents, samples and standards. 2.
