產品描述：

兔子內皮素1(ET-1)酶聯免疫試劑盒（CSB-E06951Rb）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EDN1含量。EDN1即內皮素 -1，是一種具有強大而持久血管收縮作用的多肽。在人體生理病理過程中地位重要，與心血管疾病、腫瘤等多種疾病的發生發展相關。研究聚焦于其信號轉導機制、與受體相互作用及在疾病中異常表達調控機制，以助開發相關治療策略。試劑盒檢測范圍為6.25 pg/mL-400 pg/mL，該產品適用于心血管疾病機制研究、內皮功能評估、藥物干預效果分析等基礎科研領域，支持在動物模型或離體實驗中定量分析ET-1表達動態，為血管生物學、病理生理學等研究提供穩定可靠的數據支持。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 rabbit ET-1 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)
1:1	Average %	86
	Range %	80-92
1:2	Average %	100
	Range %	91-105
1:4	Average %	96
	Range %	92-104
1:8	Average %	94
	Range %	86-98

回收率：

The recovery of rabbit ET-1 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)	95	89-99
EDTA plasma (n=4)	98	90-106

功能：

Endothelins are endothelium-derived vasoconstrictor peptides. Probable ligand for G-protein coupled receptors EDNRA and EDNRB which activates PTK2B, BCAR1, BCAR3 and, GTPases RAP1 and RHOA cascade in glomerular mesangial cells.
