New 8-OHdG Check ELISA
8-oxo-dG/8-hydroxy-2'-deoxyguanosine             最畅销的8-OHdG ELISA试剂盒

DNA氧化生物标志物

JaICA新的8羟基脱氧鸟苷(8-OHdG) ELISA试剂盒,适用于对尿液样本进行氧化应激的评估。


关于8-羟基-2'-脱氧鸟苷(8-OHdG):

8-羟基-2'-脱氧鸟苷(8-OHdG),又称为:8-羟基脱氧鸟苷;英文名称:8-hydroxy-2'-deoxyguanosine。


8-羟基-2-脱氧鸟苷(8-OHdG)是由羟基自由基、单线态氧和直接的光动力作用形成的DNA氧化损伤产物。8-OHdG可以在组织、血清、尿液和其它生物样品中检测。新的8-OHdG Check试剂盒是一种竞争性酶联免疫吸附测定(ELISA),利用对DNA损伤高度特异性的单克隆抗体(克隆#N45.1),与RNA氧化产物(例如8-羟基鸟嘌呤和8-羟基鸟苷)没有交叉反应。该试剂盒适用于从人和动物的尿液及其他生物样品中检测8-OHdG浓度。

该8羟基脱氧鸟苷(8-OHdG) ELISA试剂盒利用抗8-羟基脱氧鸟苷(8-OHdG)单克隆抗体(克隆号N45.1)对8-OHdG的高度特异性识别原理设计。在进行操作前请阅读完整说明书或咨询北京中昊新生(zhscience.com)。


JaICA提供两种类型的8-OHdG ELISA试剂盒,具有不同的检测范围。新的8-OHdG ELISA试剂盒适用于人或动物的尿液和血清样品。如果需要检测人血清、组织、细胞培养样品的8-OHdG, 我们建议使用“高灵敏的8-羟基脱氧鸟苷ELISA试剂盒(货号 #KOG-HS10E)”。
