Three samples of known concentration were tested in twenty assays to assess.

產品描述：

人免疫球蛋白A(IgA)酶聯免疫試劑盒（CSB-E07985h）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿樣本中的IgA含量。IgA是一類重要的免疫球蛋白，在黏膜免疫中發揮關鍵作用。研究發現它能阻止病原體黏附，中和毒素等。目前圍繞IgA的研究機制聚焦于其產生、調節過程，以及如何利用它開發針對感染性疾病、自身免疫病等的治療策略。試劑盒檢測范圍為0.24 ng/mL-1000 ng/mL，靈敏度為0.24 ng/mL。適用于科研場景中免疫機制研究、疾病模型分析或生物樣本中IgA水平的動態監測，例如腸道菌群與黏膜免疫關聯性研究、慢性炎癥性疾病模型的生物標志物檢測等。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of human IgA 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)
1:10000	Average %	89
	Range %	85-94
1:20000	Average %	90
	Range %	86-97
1:40000	Average %	96
	Range %	90-103
1:80000	Average %	89
	Range %	86-93

回收率：

The recovery of human IgA 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)	91	89-94
EDTA plasma (n=4)	92	88-97

標準曲線：

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