Overview 文獻(xiàn)

Product name:	Tau(Taurine) ELISA Kit
Reactivity:	General
Alternative Names:	2-Aminoethanesulfonic Acid; Tauric Acid
Assay Type:	Competitive Inhibition
Sensitivity:	4.39 ng/mL
Standard:	1000 ng/mL
Detection Range:	15.63-1000 ng/mL
Sample Type:	serum, plasma and other biological fluids
Assay Length:	2h
Research Area:	Signal transduction;
Test principle:	This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Tau protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Tau. 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 Tau 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 Tau and the recovery rates were calculated by comparing the measured value to the expected amount of Tau in samples.

Matrix	Recovery range	Average
serum(n=5)	80-95%	87%
EDTA plasma(n=5)	87-95%	91%
Heparin plasma(n=5)	82-97%	91%

線性

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