Our Elisa Kit products are perfect for the analysis of biological fluids, including Serum, plasma, tissue homogenates, cell lysates, cell culture supernatants, and other biological fluids.
ConductScience offers Elisa Kits for Analysis.
This assay has high sensitivity and excellent specificity for the detection of Estradiol (E2).
No significant cross-reactivity or interference between Estradiol (E2) and analogs was observed.
Matrices listed below were spiked with a 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(%)|
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
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.
The loss rate of activity determines the stability of the kit. The loss rate of this kit is less than 5% within the expiration date under appropriate storage conditions.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, and 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.
