產品描述：

人肝素輔因子Ⅱ(HCⅡ)酶聯免疫試劑盒（CSB-E09492h）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SERPIND1含量。SERPIND1 是重要靶點。它屬于絲氨酸蛋白酶抑制劑家族，參與凝血、纖溶等生理過程的調控。研究聚焦其與疾病關聯機制，如在血栓性疾病等發生發展中的作用，探索通過干預它來調節相關生理過程，為治療相關疾病提供新思路。試劑盒檢測范圍為1.25 pg/mL-80 pg/mL，本試劑盒適用于基礎醫學研究，可兼容多種樣本類型，包括EDTA或肝素抗凝處理的血漿樣本，以及經離心預處理的動物或人體組織勻漿，為探索HCⅡ在心血管疾病、凝血異常或肝臟代謝相關研究提供可靠工具。實驗操作基于標準ELISA流程，通過抗原 - 捕獲抗體 - 檢測抗體的特異性結合，結合酶標儀讀取吸光度值實現定量分析，實驗結果穩定且重復性良好，可滿足體外實驗中對HCⅡ表達水平動態監測的需求，例如藥物干預、基因編輯或病理模型中的分子機制研究。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 HCⅡ 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 %	92
	Range %	86-98
1:200	Average %	95
	Range %	91-100
1:400	Average %	98
	Range %	90-105
1:800	Average %	95
	Range %	89-100

回收率：

The recovery of human HCⅡspiked 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)	96	92-102
EDTA plasma (n=4)	95	90-100

功能：

Thrombin inhibitor activated by the glycosaminoglycans, heparin or dermatan sulfate. In the presence of the latter, HC-II becomes the predominant thrombin inhibitor in place of antithrombin III (AT-III). Also inhibits chymotrypsin, but in a glycosaminoglycan-independent manner.; Peptides at the N-terminal of HC-II have chemotactic activity for both monocytes and neutrophils.
