Description

ADMA(Asymmetrical Dimethylarginine) ELISA Kit

This ELISA kit uses Competitive-ELISA as the method. The microtiter plate provided in this kit has been pre-coated with ADMA. During the reaction, ADMA in the sample or standard competes with a fixed amount of  ADMA on the solid phase supporter for sites on the Biotinylated Detection Ab specific to  ADMA. Excess conjugate and unbound sample or standard are washed from the plate, and Avidin conjugated to Horseradish Peroxidase (HRP) are added to each microplate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by adding Stop Solution and the color change is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of   ADMA in the samples is then determined by comparing the OD of the samples to the standard curve.

Specificity

This kit recognizes ADMA in samples. No significant cross-reactivity or interference between ADMA and analogues was observed.

Typical Data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level ADMA were tested 20 times on one plate, respectively.

Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level ADMA were tested on 3 different plates, 20 replicates in each plate.

Recovery

The recovery of ADMA 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=5)87-10294
EDTA plasma (n=5)96-111102
Cell culture media (n=5)94-108101

Linearity

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