Specificity of the Wide-range ELISA Kit for Corticosterone (Cort)
This assay has high sensitivity and excellent specificity for detection of Wide-range Corticosterone (Cort).
No significant cross-reactivity or interference between Wide-range Corticosterone (Cort) and analogues was observed.
Recovery of the Wide-range ELISA Kit for Corticosterone (Cort)
Matrices listed below were spiked with certain level of Wide-range Corticosterone (Cort) and the recovery rates were calculated by comparing the measured value to the expected amount of Wide-range Corticosterone (Cort) in samples.
| Matrix | Recovery range (%) | Average(%) |
| serum(n=5) | 80-99 | 90 |
| EDTA plasma(n=5) | 81-92 | 88 |
| heparin plasma(n=5) | 87-97 | 93 |
Precision of the Wide-range ELISA Kit for Corticosterone (Cort)
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Wide-range Corticosterone (Cort) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Wide-range Corticosterone (Cort) 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 Wide-range ELISA Kit for Corticosterone (Cort)
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Wide-range Corticosterone (Cort) 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) | 84-96% | 81-102% | 88-95% | 87-102% |
| EDTA plasma(n=5) | 90-101% | 78-93% | 78-97% | 93-102% |
| heparin plasma(n=5) | 84-96% | 98-105% | 81-104% | 89-103% |
Stability of the Wide-range ELISA Kit for Corticosterone (Cort)
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.

Test principle of the Wide-range ELISA Kit for Corticosterone (Cort)
This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Wide-range Corticosterone (Cort) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Wide-range Corticosterone (Cort) and unlabeled Wide-range Corticosterone (Cort) (Standards or samples) with the pre-coated antibody specific to Wide-range Corticosterone (Cort). 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 Wide-range Corticosterone (Cort) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Wide-range Corticosterone (Cort) in the sample.
