产品描述

    CD81（Cluster of Differentiation 81），又称为TAPA-1 (Target of the antiproliferative antibody 1)，是一种细胞表面蛋白，广泛存在于各种细胞类型中，包括B和T淋巴细胞。CD81在免疫应答中起着重要作用，它参与B和T细胞的激活、增殖、分化等过程，同时还参与多种病毒感染。人体内CD81的含量与免疫系统的功能紧密相关。

测定原理

quantitative

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.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.

线性度

To assess the linearity of the assay, samples were spiked with high concentrations of human CD81 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)
1:1		Average %		92
		Range %		88-101
1:2		Average %		97
		Range %		92-105
1:4		Average %		92
		Range %		87-100
1:5		Average %		95
		Range %		90-100

回收率

The recovery of human CD81 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)		97		95-100
EDTA plasma (n=4)		98		94-102
