研究人员报告了两种静脉注射引发剂,以恢复更多的ctDNA。

研究人员试图通过减弱体内循环肿瘤DNA(ctDNA)的清除率来短暂提高抽血样本中循环肿瘤DNA的水平。

but their sensitivity remains limited by the scarcity of analytes such as cell-free DNA (cfDNA) in blood. Improvements to sensitivity have primarily relied on enhancing sequencing technology ex vivo. We sought to transiently augment the level of circulating tumor DNA (ctDNA) in a blood draw by attenuating its clearance in vivo. We report two intravenous priming agents given 1 to 2 hours before a blood draw to recover more ctDNA. Our priming agents consist of nanoparticles that act on the cells responsible for cfDNA clearance and DNA-binding antibodies that protect cfDNA. In tumor-bearing mice。
