Overview

Product name:	VB6(Vitamin B6) ELISA Kit
Reactivity:	General
Alternative Names:	Pyridoxine
Assay Type:	Competitive Inhibition
Sensitivity:	1.43 ng/mL
Standard:	300 ng/mL
Detection Range:	4.69-300 ng/mL
Sample type:	serum, plasma and other biological fluids
Assay length:	2h
Research Area:	Nutrition metabolism;Hormone metabolism;
Test principle:	This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with VB6. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to VB6. 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 VB6 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 VB6 and the recovery rates were calculated by comparing the measured value to the expected amount of VB6 in samples.

Matrix	Recovery range	Average
serum(n=5)	84-92%	87%
EDTA plasma(n=5)	95-104%	98%
Heparin plasma(n=5)	82-90%	87%

线性

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of VB6 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
