產品描述：

人核糖核酸酶7(RNASE7)酶聯免疫試劑盒（CSB-EL019798HU）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、尿液、唾液、組織培養上清液、組織勻漿、細胞裂解物樣本中的RNASE7含量。RNASE7是具有研究價值的靶點。它在人體的免疫防御等方面可能發揮重要作用。相關研究機制主要圍繞其對病原體的作用展開，如它可能通過降解病原體的核酸來抑制其活性，進而抵御感染，后續還需更多研究深入明晰其作用細節。試劑盒檢測范圍為1.56 ng/mL-100 ng/mL，適用于體外研究RNASE7在感染性疾病機制、上皮免疫調控或黏膜屏障功能等領域的表達規律，例如分析不同病理狀態下唾液或尿液中RNASE7的動態變化，或評估體外培養細胞受病原體刺激后的分泌水平，為探索其在先天免疫中的功能提供可靠工具。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。

線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of human RNASE7 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 %	100
	Range %	95-105
1:2	Average %	98
	Range %	93-103
1:4	Average %	89
	Range %	80-95
1:8	Average %	88
	Range %	82-99

回收率：

The recovery of human RNASE7 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)	100	95-105
EDTA plasma (n=4)	104	100-109

功能：

Exhibits a potent RNase activity. Has broad-spectrum antimicrobial activity against many pathogenic microorganisms and remarkably potent activity (lethal dose of 90% < 30 nM) against a vancomycin resistant Enterococcus faecium. Causes loss of bacterial membrane integrity. Probably contributes to urinary tract sterility. Bactericidal activity is independent of RNase activity.
