產品描述：

大鼠分泌型免疫球蛋白A(sIgA)酶聯免疫試劑盒（CSB-E08412r）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sIgA含量。sIgA即分泌型免疫球蛋白A，是黏膜免疫的重要效應分子。它可阻止病原體黏附上皮細胞、中和毒素及病毒等。研究主要聚焦其產生機制、在黏膜免疫防御中的作用機制等，對揭示機體抗感染免疫及開發相關疫苗等有重要意義。試劑盒檢測范圍為0.78 ng/mL-50 ng/mL，在科研領域，本試劑盒可用于研究大鼠模型中黏膜免疫相關疾病（如腸道炎癥、呼吸道感染）的發病機制，評估免疫調節劑或益生菌干預效果，亦可應用于營養學、毒理學研究中黏膜屏障功能的動態監測。其多樣本類型兼容性為實驗設計提供靈活性，例如通過組織勻漿檢測局部黏膜sIgA表達，或通過體液樣本評估系統免疫狀態。本產品嚴格遵循質量控制標準，提供標準品及預包被板等完整實驗組件，確保實驗數據的穩定性和可重復性，為科研人員探索黏膜免疫調控網絡提供可靠工具。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 rat sIgA 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)
1:100	Average %	102
	Range %	97-106
1:200	Average %	90
	Range %	86-96
1:400	Average %	97
	Range %	92-103
1:800	Average %	88
	Range %	84-92

回收率：

The recovery of rat sIgA 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)	84	80-88
EDTA plasma (n=4)	95	91-99
