Test Principle

This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with ANP. During the reaction, ANP in the sample or standard competes with a fixed amount of ANP on the solid phase supporter for sites on the Biotinylated Detection Ab specific to ANP. 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 ANP 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 ANP were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level ANP were tested on 3 different plates, 20 replicates in each plate.

The recovery of ANP 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) 86-100 92
EDTA plasma(n=8) 94-104 99
Cell culture media(n=8) 92-107 99


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

Asked: Does this kit cross-react with mouse ANP?



adminSubmitted [ Jun 15 2018 ]

Answered: Hi Marina, Thanks for your inquiry. The cross-reactivity with the mouse ANP is 22.4% in our lab as the identity of the immunogen sequences is high. Any other questions, pls feel free to contact us. Best regards.
