Test principle: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Rat F protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat F. 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 Rat F 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 F and the recovery rates were calculated by comparing the measured value to the expected amount of F in samples.
Matrix Recovery range Average
serum(n=5) 95-107% 101%
EDTA plasma(n=5) 81-95% 88%
Heparin plasma(n=5) 87-95% 91%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of F 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) 91-103% 85-94% 79-96% 98-105%
EDTA plasma(n=5) 82-93% 95-102% 93-101% 87-96%
Heparin plasma(n=5) 82-93% 89-97% 85-94% 78-96%
