显微注射是最常用的线虫遗传操作工具。然而,转基因秀丽隐杆线虫通常是由人工操作员在显微镜下手动注射产生的,这可能非常耗时。在《自然-通讯》(Nature Communications)杂志上,Pan 等人报道了一种用于秀丽隐杆线虫显微注射的新型自动机器人系统,该系统在高通量转基因研究方面显示出巨大潜力。该方法集成了一个计算机控制的微流体装置(可旋转并固定蠕虫)和一个机器人系统(可精确控制注射移液管的运动),从而可将蠕虫精确注射到特定器官。为了验证他们的系统,研究人员给蠕虫注射了质粒 DNA 溶液和核糖核蛋白复合物,以创建基因组编辑动物。他们的研究表明,机器人系统能以平均44.5秒/只蠕虫的速度进行单性腺臂注射,成功率高,比人工注射快2-3倍。这是首次报道可靠的机器人系统可将质粒高精度地注入蠕虫体内的目标器官。该方法可用于广泛的应用领域:Pan, P. et al.Nat.15, 8848 (2024)
