產品描述：豬分泌型免疫球蛋白A(sIgA)酶聯免疫試劑盒（CSB-E12063p）為競爭法ELISA試劑盒，定量檢測血清、血漿、組織培養上清液、組織勻漿樣本中的sIgA含量。sIgA即分泌型免疫球蛋白A，是黏膜免疫的主要效應分子。其能在黏膜表面阻止病原體黏附與入侵，中和毒素等。研究中聚焦于其產生機制、影響因素等，以探索增強sIgA水平或功能的方法，用于防治黏膜感染等疾病。試劑盒檢測范圍為0.15 μg/mL-37.5 μg/mL，適用于動物免疫機制研究，如評估腸道感染模型中的黏膜免疫應答、疫苗效價驗證或飼料添加劑對免疫調節的影響等領域。支持科研人員在體外實驗中系統性分析sIgA的動態變化，為豬類免疫學研究提供可靠工具。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。

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. -
線性度：
To assess the linearity of the assay, samples were spiked with high concentrations of pig sIgA in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

■ 常見問題解答
Q:
Could you indicate me if your kit could be valid for feces samples? Any recommendations for this type of samples?
A:
Thanks for your inquiry.
Here advice the customer to arrange preliminary experiment if you want to detect feces sample.
Below is our sample method for your reference:
Feces Dilute samples with appropriate Sample Diluent.
This can be achieved by adding 0.1g sample to appropriate Sample Diluent.
Remove particulates by centrifugation for 10 minutes at 4000x g at 2-8°C and assay immediately.Pls let me know if you have any further questions. Thank you.
