Product Details

Properties

Assay type	Sandwich-ELISA
Format	96T/48T/24
Assay time	3.5h
Detection range	0.16-10 ng/mL
Sensitivity	0.10 ng/mL
Sample type &Sample volume	serum, plasma and other biological fluids; 100μL
Specificity	This kit recognizes Rat DAO in samples. No significant cross-reactivity or interference between Rat DAO and analogues was observed.
Reproducibility	Both intra-CV and inter-CV are < 10%.
Application	This ELISA kit applies to the in vitro quantitative determination of Rat DAO concentrations in serum, plasma and other biological fluids.

Test Principle

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat DAO. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat DAO and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat DAO, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat DAO. You can calculate the concentration of Rat DAO in the samples by comparing the OD of the samples to the standard curve.

Technical Data

Precision

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

	Intra-assay Precision			Inter-assay Precision
Sample	1	2	3	1	2	3
n	20	20	20	20	20	20
Mean (ng/mL)	0.46	1.19	4.05	0.45	1.02	4.91
Standard deviation	0.02	0.06	0.20	0.03	0.05	0.23
CV (%)	4.35	5.04	4.94	6.67	4.90	4.68

Recovery

The recovery of Rat DAO 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)	102-113	105
EDTA plasma (n=8)	84-96	92
Cell culture media (n=8)	86-100	94

Linearity

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

Assay Procedures

	1. Add 100μL standard or sample to the wells. Incubate for 90 min at 37°C
	2. Discard the liquid, immediately add 100μL Biotinylated Detection Ab working solution to each well. Incubate for 60 min at 37°C
	3. Aspirate and wash the plate for 3 times
	4. Add 100μL HRP conjugate working solution. Incubate for 30 min at 37°C. Aspirate and wash the plate for 5 times
	5. Add 90μL Substrate Reagent. Incubate for 15 min at 37°C
	6. Add 50μL Stop Solution
	7. Read the plate at 450nm immediately. Calculation of the results
