Application	This ELISA kit applies to the in vitro quantitative determination of E3 concentrations in serum and plasma.

Test Principle

This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Porcine E3. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Porcine E3 are added to the micro ELISA plate wells. Porcine E3 in samples (or standards) competes with a fixed amount of E3 on the solid phase supporter for sites on the HRP linked detection antibody specific to E3. Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. 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±2 nm. The concentration of Porcine E3 in the samples is then determined by comparing the OD of the samples to the standard curve.

Kit components & Storage

An unopened kit can be stored at 2-8℃ for 6 months. After test, the unused wells and reagents should be stored according to the table.

Technical Data

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level E3 were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level E3 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 (pg/mL)	10.34	30.45	79.41	9.75	27.45	81.51
Standard deviation	0.65	1.75	2.80	0.49	1.27	3.86
CV (%)	6.30	5.76	3.53	5.04	4.64	4.74

Recovery

The recovery of E3 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)	89-103	96
EDTA plasma(n=8)	88-102	96

Linearity

Samples were spiked with high concentrations of Porcine E3 and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
