Application This ELISA kit applies to the in vitro quantitative determination of ALD concentrations in serum, plasma and other biological fluids.

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.

Technical Data


Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level ALD were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level ALD were tested on 3 different plates, 20 replicates in each plate.

The recovery of ALD spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

Sample Type Range (%) Average Recovery (%)
Serum(n=8) 86-98 91
EDTA plasma(n=8) 96-112 102
Cell culture media(n=8) 90-102 96


Samples were spiked with high concentrations of ALD and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
