Specificity of the CLIA Kit for Estradiol (E2)

This assay has high sensitivity and excellent specificity for detection of Estradiol (E2).
No significant cross-reactivity or interference between Estradiol (E2) and analogues was observed.

Recovery of the CLIA Kit for Estradiol (E2)

Matrices listed below were spiked with certain level of Estradiol (E2) and the recovery rates were calculated by comparing the measured value to the expected amount of Estradiol (E2) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 85-101 92
EDTA plasma(n=5) 87-104 93
heparin plasma(n=5) 90-97 93

Precision of the CLIA Kit for Estradiol (E2)

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Estradiol (E2) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Estradiol (E2) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%

Linearity of the CLIA Kit for Estradiol (E2)

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Estradiol (E2) 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) 89-96% 91-105% 98-105% 82-98%
EDTA plasma(n=5) 82-104% 92-101% 83-97% 80-103%
heparin plasma(n=5) 85-92% 88-99% 79-105% 90-98%

Stability of the CLIA Kit for Estradiol (E2)

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.

7. Read RLU value immediately.

Test principle of the CLIA Kit for Estradiol (E2)

The microplate provided in this kit has been pre-coated with a monoclonal antibody specific to Estradiol (E2). A competitive inhibition reaction is launched between biotin labeled Estradiol (E2) and unlabeled Estradiol (E2) (Standards or samples) with the pre-coated antibody specific to Estradiol (E2). 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 Estradiol (E2) in the sample. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is reverse proportional to the Estradiol (E2) level in the sample or standard.
