HEK293 细胞是一种人胚肾细胞系,因其对生长对培养环境要求不高、易于转染等特点,被广泛用于治疗性蛋白生产、疫苗中的病毒样颗粒生产、细胞和基因治疗中的病毒包装或用于开展相关的科学研究。但也有实验证明,HEK293注射入裸鼠中可成瘤,所以HEK293细胞残留成分是生物制品质量控制中一个重要环节,需要被控制在可接受的水平。




1、灵敏度高:能够准确定量低至6 fg/μL的HEK293细胞DNA;
2、特异性强:具有HEK293 DNA特异性,与无关DNA不存在交叉反应;
3、准确性和精密度高:

4、稳定性好:冻融循环10次,试剂盒性能不受影响;
5、耐用性强:DNA碎片化程度不影响检测结果,碎片化DNA回收率高;适配多款qPCR仪器如Bio-Rad(CFX96 Optic Module)、Thermo Scientific(ABI Quant Studio5; ABI Step OnePlus)、上海宏石医疗科技(SLAN-96S)

6、操作时间短:搭配使用Auto-Pure32A全自动核酸提取仪,3小时内完成全部检测流程。


1、磁珠法样品前处理试剂盒:可以手动提取,也可以与全自动核酸提取仪搭配使用;

2、Auto-Pure32A全自动核酸提取仪:搭配翌圣磁珠法样本前处理试剂盒解放双手,自动化提取样本中的宿主细胞DNA残留。
