| Application: | This ELISA kit applies to the in vitro quantitative determination of Ang1-7 concentrations in. |
This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Ang1-7. During the reaction, Ang1-7 in the sample or standard competes with a fixed amount of Ang1-7 on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Ang1-7. 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 ± 2 nm. The concentration of Ang1-7 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): 3 samples with low, mid range and high level Ang1-7 were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Ang1-7 were tested on 3 different plates, 20 replicates in each plate.

Recovery
The recovery of Ang1-7 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.
| Sample Type | Range (%) | Average Recovery (%) |
| Serum(n=8) | 93-107 | 100 |
| EDTA plasma(n=8) | 87-100 | 93 |
| Cell culture media(n=8) | 95-107 | 101 |
| Kit Components: | An unopened kit can be stored at 2-8℃ for 1 month. If the kit is not supposed to be used within 1 month, store the components separately according to the following conditions once the kit is received.
