Recovery

Matrices listed below were spiked with certain level of recombinant Endothelin 1 (EDN1) and the recovery rates were calculated by comparing the measured value to the expected amount of Endothelin 1 (EDN1) in samples.

Matrix	Recovery range (%)	Average(%)
serum(n=5)	80-101	86
EDTA plasma(n=5)	84-93	89
heparin plasma(n=5)	80-93	88

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Endothelin 1 (EDN1) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Sample	1:2	1:4	1:8	1:16
serum(n=5)	78-94%	91-98%	96-104%	91-98%
EDTA plasma(n=5)	79-88%	80-105%	97-104%	94-102%
heparin plasma(n=5)	86-93%	78-99%	80-101%	78-102%

Precautions

The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Notes

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Endothelin 1 (EDN1) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Endothelin 1 (EDN1) and unlabeled Endothelin 1 (EDN1) (Standards or samples) with the pre-coated antibody specific to Endothelin 1 (EDN1). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Endothelin 1 (EDN1) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Endothelin 1 (EDN1) in the sample.
