Lablisa® Rat Ang-Ⅱ (Angiotensin Ⅱ) ELISA Kit
Catalog No.: LAB13279
| Reactivity | Rat |
| Detection Range | 15.63-1000pg/mL |
| Sensitivity | 9.38pg/mL |
Description
This ELISA kit uses the Competitive-ELISA principle. The micro-ELISA plate provided in this kit has been pre-coated with Rat Ang-Ⅱ. During the reaction, Rat Ang-Ⅱ in the sample or standard competes with a fixed amount of Rat Ang-Ⅱ on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Rat Ang-Ⅱ. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm. The concentration of Rat Ang-Ⅱ in tested samples can be calculated by comparing the OD of the samples to the standard curve.

Precision
Intra-assay Precision (Precision within an assay) ：CV%<8% Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision (Precision between assays) ：CV%<10% Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.
Recovery
Matrices listed below were spiked with certain level of recombinant Rat Ang-Ⅱ and the recovery rates were calculated by comparing the measured value to the expected amount of Rat Ang-Ⅱ in samples.
| Matrix | Recovery range | Average |
|---|---|---|
| serum (n=8) | 93-100% | 96% |
| EDTA plasma (n=8) | 94-102% | 99% |
| Cell culture media (n=8) | 87-96% | 91% |
Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Rat Ang-Ⅱ and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
| Matrix | 1:2 | 1:4 | 1:8 | 1:16 |
|---|---|---|---|---|
| serum (n=8) | 94-102% | 97-107% | 98-105% | 98-107% |
| EDTA plasma (n=8) | 95-101% | 93-102% | 91-99% | 94-102% |
| Cell culture media (n=8) | 90-98% | 98-104% | 97-105% | 98-106% |
