INTENDED USE
The kit is a sandwich enzyme immunoassay for the in vitro quantitative measurement of ATP2A2 in human tissue homogenates, cell lysates or other biological fluids.
DETECTION RANGE
0.312-20ng/mL. The standard curve concentrations used for the ELISA’s were 20ng/mL, 10ng/mL, 5ng/mL, 2.5ng/mL, 1.25ng/mL, 0.625ng/mL, 0.312ng/mL.
SENSITIVITY
The minimum detectable dose of ATP2A2 is typically less than 0.126ng/mL.
The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined by adding two standard deviations to the mean optical density value of twenty zero standard replicates and calculating the corresponding concentration.
SPECIFICITY
This assay has high sensitivity and excellent specificity for detection of ATP2A2.
No significant cross-reactivity or interference between ATP2A2 and analogues was observed.

Test principle
The microtiter plate provided in this kit has been pre-coated with an antibody specific to the index. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to the index. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain the index, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of the index in the samples is then determined by comparing the O.D. of the samples to the standard curve.
Recovery
Matrices listed below were spiked with certain level of recombinant ATP2A2 and the recovery rates were calculated by comparing the measured value to the expected amount of the index in samples.
| Matrix | Recovery range (%) | Average(%) |
| serum(n=5) | 81-93 | 86 |
| EDTA plasma(n=5) | 80-97 | 88 |
| heparin plasma(n=5) | 90-101 | 95 |
Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of the index 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) | 82-96% | 83-98% | 81-99% | 93-101% |
| EDTA plasma(n=5) | 88-101% | 86-95% | 90-102% | 80-93% |
| heparin plasma(n=5) | 80-91% | 82-90% | 95-104% | 79-95% |
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%
Stability
The stability of ELISA 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 conditions.
Note:
To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
