Performance
| Typical data |
The following data was generated by the Quality Control Department, under controlled laboratory conditions (ambient temperature: 18-25 °C, relative humidity: 35-75%) using standardized procedures (TMB reaction at 37 °C in the dark for 15 minutes, followed by termination and OD measurement). These values are provided for reference only.
Actual results may vary due to differences in laboratory conditions, operator technique, and equipment. Users are required to generate a standard curve using their own experimental data.

| Precision |
Intra-assay Precision (Within-run Precision): Three samples representing low, mid, and high concentrations of Human IL-6 were tested 20 times on a single plate.
Inter-assay Precision (Between-run Precision): Three samples representing low, mid, and high concentrations of Human IL-6 were tested on three separate plates, with 20 replicates per plate, to assess variability among assays.

| Recovery |
The recovery of Mouse ACE2 was evaluated by spiking samples at low, mid, and high concentrations across the assay range in various sample matrices.
The assay performance was assessed by comparing the measured concentrations to the expected spiked amounts to determine the percent recovery.
|
|||||||||||||||||||||||||||||||||||||||||||||
| Linearity |
Linearity of the assay was evaluated by spiking samples with high concentrations of Mouse ACE2 and performing serial dilutions using Standard & Sample Diluent to produce concentrations spanning the assay's dynamic range.
The measured values were then compared to the expected concentrations to assess the linearity of response.

| Stability |
Each kit batch is subjected to accelerated stability testing and real-time stability monitoring. Sample performance is evaluated after storage at 37 °C for 10 days to assess the impact of elevated temperature on assay reliability and reagent integrity.

Test Principle
This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to ACE2 . Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for ACE2 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain ACE2 , biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of ACE2 . You can calculate the concentration of ACE2 in the samples by comparing the OD of the samples to the standard curve.
Background
ACE2 is a member of the angiotensin-converting enzyme family of dipeptidyl carboxydipeptidases. It catalyzes the cleavage of the decapeptide angiotensin I into angiotensin-(1-9) and angiotensin II (potent vasoconstrictor) into the vasodilator angiotensin-(1-7). ACE2 is a type I membrane protein that functions as a carboxypeptidase. It cleaves between a proline and a single hydrophobic/basic residue from the COOH-terminus of its substrates. ACE2 is a zinc metalloprotease with considerable homology to angiotensin I-converting enzyme (ACE),both enzymes contain the typical HEXXH zinc-binding motif,ACE has two catalytic sites and ACE2 has only one,and ACE2 is not inhibited by ACE inhibitors captopril,lisinopril,and enalaprilat. Studies in mice showed that disruption of ACE2 induced a severe cardiac contractility defect and increased angiotensin II levels in heart. Human ACE2 has been identified as the receptor for SARS (severe acute respiratory syndrome)-coronavirus.
