“Quanticon” Human NSE(Neuron Specific Enolase) ELISA Kit

Principle

This assay employs the quantitative sandwich enzyme immunoassay technique. The micro plate provided in this kit has been pre-coated with an antibody specific to Human NSE. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human NSE. 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 Human NSE, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color change is measured spectrophotometrically at a wavelength of 450nm±3nm. The concentration of NSE in the samples is then determined by comparing the OD of the samples to the standard curve.

Specification

Precision

Mean coefficient of variation for Intra-Assay and Inter-Assay: 3 samples with low, middle and high level concentration were tested for repeat multiple times, respectively.The results showed that the coefficient of variation of the kits was less than 10%, which met the precision quality control standard.

Intra-Assay: CV<5%

Inter-Assay: CV<8%
