Assay Type: Competitive Inhibition
Sensitivity: 1.17 ng/mL
Standard: 200 ng/mL
Range: 3.13-200 ng/mL
Sample Type: serum, plasma and other biological fluids

Test principle: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Human Anti-SNCa protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human Anti-SNCa. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. 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 Human Anti-SNCa in the samples is then determined 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 Anti-SNCa and the recovery rates were calculated by comparing the measured value to the expected amount of Anti-SNCa in samples.
Matrix Recovery range Average
serum(n=5) 81-95% 88%
EDTA plasma(n=5) 94-105% 98%
Heparin plasma(n=5) 81-95% 88%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Anti-SNCa 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=5) 78-92% 79-93% 91-98% 89-102%
EDTA plasma(n=5) 85-94% 92-101% 87-96% 82-90%
Heparin plasma(n=5) 81-94% 93-107% 93-102% 91-105%
