產品描述：

小鼠維生素K依賴性蛋白S(PROS1)酶聯免疫試劑盒（CSB-EL018754MO）為競爭法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的PROS1含量。PROS1編碼的蛋白S是一種維生素K依賴的血漿糖蛋白，作為天然抗凝劑發揮作用。研究機制方面，它可增強活化蛋白C的活性以滅活凝血因子，還能以不依賴活化蛋白C的方式抑制凝血酶原酶復合物的形成，進而調控凝血過程。試劑盒檢測范圍為6.25 ng/mL-400 ng/mL，適用于科研場景下的小鼠模型研究，例如探究凝血功能障礙機制、血栓性疾病動物模型的蛋白表達動態變化，或評估肝腎功能異常對PROS1合成的影響。其寬泛的線性范圍與多類型樣本兼容性（包括組織勻漿）可為心血管疾病、免疫調節及器官特異性研究提供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 human APOC4 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)
1:200	Average %	92
Range %	88-96
1:400	Average %	87
Range %	84-90
1:800	Average %	95
Range %	91-99
1:1600	Average %	97
Range %	92-102

回收率：

The recovery of human APOC4 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)	94	90-98
EDTA plasma (n=4)	98	94-103

功能：

Anticoagulant plasma protein; it is a cofactor to activated protein C in the degradation of coagulation factors Va and VIIIa. It helps to prevent coagulation and stimulating fibrinolysis.
