Datasheet

 
Test Principle

This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with ALD. During the reaction, ALD in the sample or standard competes with a fixed amount of ALD on the solid phase supporter for sites on the Biotinylated Detection Ab specific to ALD. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of ALD in tested samples can be calculated by comparing the OD of the samples to the standard curve.

Assay Procedures:
 
Typical Data:
ALD ELISA Standard Curve Typical data are for reference only and curves should be replotted for each experiment. The Logistics function is recommended for fitting.
 
Precision:
Intra-assay precision (intra-assay precision): Low, medium, and high levels of ALD were measured on a single plate 20 times at each level. Inter-assay Precision (interassay precision): Samples containing low, intermediate, and high levels of ALD were assayed 20 times per plate on 3 different plates.

Linearity:
A high concentration of ALD is added to the sample, which is then diluted with a standard and a sample diluent to bring the value of the sample within the detection range.
