產品詳情

產品描述：

人補體片段4d(C4d)酶聯免疫試劑盒（CSB-E14192h）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C4d含量。C4d是經典補體激活途徑的相關產物，可反映補體系統激活狀況。研究機制上，其產生與C4的裂解有關，檢測C4d水平能輔助判斷補體激活程度，在免疫相關疾病，如移植排斥反應等的診斷和病情監測中有重要價值。試劑盒檢測范圍為0.78 ng/mL-50 ng/mL，適用于體外研究場景，如探討補體系統在心血管疾病、腎臟病理或免疫復合物相關疾病中的作用機制，也可用于評估實驗動物模型或細胞實驗中補體激活水平，為免疫相關基礎研究提供精準定量工具。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 human C4d 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 %	103
	Range %	94-108
1:200	Average %	98
	Range %	90-104
1:400	Average %	89
	Range %	82-93
1:800	Average %	95
