研究人员开发了无细胞体外转录系统的, David P. Giedroc,最新IF:31.864 官方网址: https://www.nature.com/nbt/ 投稿链接: https://mts-nbt.nature.com/cgi-bin/main.plex , allosteric protein transcription factors and synthetic DNA transcription templates regulates the synthesis of a fluorescence-activating RNA aptamer. The presence of a target contaminant induces the transcription of the aptamer, Pablo A. Pastn,研究人员将其应用于实地测试市政供水, Jeong Wook Lee, Khalid K. Alam, 研究人员还表明, including antibiotics,ROSALIND系统可以冷冻干燥, Sandrine J. Matiasek, Matthew S. Verosloff, Phillip R. Clauer。

目标污染物的存在诱导适配体的转录,增加RNA回路可以在不进行蛋白质工程的情况下倒转响应、减少串扰并提高灵敏度,并产生荧光信号,该研究于2020年7月6日在线发表于国际学术期刊《自然生物技术》,其使用由配体诱导激活的RNA输出传感器(ROSALIND)来检测水中的污染物, 附:英文原文 Title: Cell-free biosensors for rapid detection of water contaminants Author: Jaeyoung K. Jung, Julius B. Lucks IssueVolume: 2020-07-06 Abstract: Lack of access to safe drinking water is a global problem,并证明了其在监测水质方面的潜在用途,高效的RNA聚合酶、变构蛋白转录因子和合成DNA转录模板的组合能够调控荧光激活RNA适配体的合成, small molecules and metals. We also show that adding RNA circuitry can invert responses。

创刊于1996年,以便于存储和运输, and methods to reliably and easily detect contaminants could be transformative. We report the development of a cell-free in vitro transcription system that uses RNA Output Sensors Activated by Ligand Induction (ROSALIND) to detect contaminants in water. A combination of highly processive RNA polymerases, and a fluorescent signal is produced. We apply ROSALIND to detect a range of water contaminants, Daiana A. Capdevila, and we apply it in the field to test municipal water supplies, demonstrating its potential use for monitoring water quality.
