產(chǎn)品描述：

綿羊免疫球蛋白E(IgE)酶聯(lián)免疫試劑盒（CSB-E13683Sh）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的IgE含量。IgE是一種在哺乳動物體內(nèi)發(fā)現(xiàn)的抗體，含量極低，主要由黏膜下淋巴組織中的效應(yīng)B細(xì)胞合成。它是一種親細(xì)胞抗體，可引起I型變態(tài)反應(yīng)，如過敏。研究顯示，IgE與高親和力受體FcεRI相互作用是過敏反應(yīng)的核心環(huán)節(jié)，其激活機(jī)制涉及FcεRI從二聚體轉(zhuǎn)變?yōu)閱误w，從而激活下游信號通路。試劑盒檢測范圍為125 ng/mL-8000 ng/mL，適用于科研領(lǐng)域?qū)d羊免疫狀態(tài)評估、過敏性疾病機(jī)制研究或寄生蟲感染模型的免疫指標(biāo)分析，為畜牧學(xué)、獸醫(yī)學(xué)及比較免疫學(xué)研究提供可靠工具本品僅用于科研，不用于臨床診斷，產(chǎn)品具體參數(shù)及操作步驟詳見產(chǎn)品說明書。

線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of sheep IgE 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 %	86
	Range %	80-94
1:2	Average %	97
	Range %	92-100
1:4	Average %	90
	Range %	85-95
1:8	Average %	95
	Range %	87-99

回收率：

The recovery of sheep IgE 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	89-102
EDTA plasma (n=4)	96	91-100
