Test principle:	The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to TransformingGrowth Factor Beta 1(TGF-b1). Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to TransformingGrowth Factor Beta 1(TGF-b1). 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 TransformingGrowth Factor Beta 1(TGF-b1), 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 TransformingGrowth Factor Beta 1(TGF-b1) in the samples is then determined by comparing the OD of the samples to the standard curve.

精密度

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.

回收率

Matrices listed below were spiked with certain level of recombinant General TGF-b1 and the recovery rates were calculated by comparing the measured value to the expected amount of General TGF-b1 in samples.

Matrix	Recovery range	Average
serum(n=5)	79-97%	88%
EDTA plasma(n=5)	95-107%	101%
Heparin plasma(n=5)	96-107%	102%

线性

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of General TGF-b1 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
