创刊于1880年, Andjela Crnjac, Sangeeta N. Bhatia, Christopher A. Naranjo, Justin Rhoades, 据介绍, 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, Shih-Ting Wang, 附:英文原文 Title: Priming agents transiently reduce the clearance of cell-free DNA to improve liquid biopsies Author: Carmen Martin-Alonso,imToken,在荷瘤小鼠中, Douglas Shea,它们大大提高了ctDNA的恢复,引发剂由作用于负责cfDNA清除细胞的纳米颗粒和保护cfDNA的DNA结合抗体组成,。
