Elisa kit for Angiotensin 2
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.
Elisa Kit for Angiotensin 2 has high sensitivity and excellent specificity for the detection of Angiotensin II (AngII). ConductScience offers Elisa Kits for the analysis of biological fluids.
Specificity
This assay has high sensitivity and excellent specificity for the detection of Angiotensin II (AngII).
No significant cross-reactivity or interference between Angiotensin II (AngII) and analogs was observed.
Recovery
Matrices listed below were spiked with a certain level of recombinant Angiotensin II (AngII). The recovery rates were calculated by comparing the measured value to the expected amount of Angiotensin II (AngII) in samples.
| Matrix | Recovery range (%) | Average(%) |
|---|---|---|
| serum(n=5) | 86-102 | 90 |
| EDTA plasma(n=5) | 83-97 | 91 |
| heparin plasma(n=5) | 79-96 | 78 |
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level Angiotensin II (AngII) were tested 20 times on one plate, respectively.Â
Inter-assay Precision (Precision between assays): 3 samples with low, middle, and high-level Angiotensin II (AngII) were tested on 3 different plates, with 8 replicates in each plate.Â
CV(%) = SD/meanX100Â
Intra-Assay: CV<10%Â
Inter-assay: CV<12%Â
Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Angiotensin II (AngII) 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) | 82-104% | 97-105% | 88-104% | 94-101% |
| EDTA plasma(n=5) | 96-105% | 90-97% | 91-99% | 96-103% |
| heparin plasma(n=5) | 92-102% | 79-92% | 97-104% | 93-101% |
Stability
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.Â
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.
