Detection range6.859-5000pg/mL The standard curve concentrations used for the ELISA’s were 5000pg/mL, 1666.67pg/mL, 555.56pg/mL, 185.19pg/mL, 61.728pg/mL, 20.576pg/mL, 6.859pg/mL
SensitivityThe minimum detectable dose of this kit is typically less than 2.43pg/mL.
Specificity
This assay has high sensitivity and excellent specificity for detection of Amyloid Precursor Protein (APP).
No significant cross-reactivity or interference between Amyloid Precursor Protein (APP) and analogues was observed.
Recovery
Matrices listed below were spiked with certain level of recombinant Amyloid Precursor Protein (APP) and the recovery rates were calculated by comparing the measured value to the expected amount of Amyloid Precursor Protein (APP) in samples.
Matrix Recovery range (%) Average(%)
serum(n=5)90-10298
EDTA plasma(n=5)92-10196
heparin plasma(n=5)79-9083
Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Amyloid Precursor Protein (APP) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Amyloid Precursor Protein (APP) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%
Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Amyloid Precursor Protein (APP) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

heparin plasma(n=5)79-101%94-102%93-104%84-101%
Stability
The stability of 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 condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, 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.

Test principle
The microtiter plate provided in this kit has been pre-coated with an antigen. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated secondary antibody. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is proportional to the Amyloid Precursor Protein (APP) level in the sample or standard.
