線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of bovine VA in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:10	Average %	95
	Range %	91-99
1:20	Average %	103
	Range %	99-107
1:40	Average %	98
	Range %	93-103
1:80	Average %	92
	Range %	89-95

回收率：

The recovery of bovine VA spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Sample Type	Average % Recovery	Range
Serum (n=5)	99	93-104
EDTA plasma (n=4)	89	83-95

標(biāo)準(zhǔn)曲線：

These standard curves are provided for demonstration only. A standard curve should be generated for each set of samples assayed.

最新研究進(jìn)展：

最新研究表明，VA蛋白在細(xì)胞分化、免疫應(yīng)答和炎癥反應(yīng)等生物學(xué)過(guò)程中起著重要的作用。
