在这里,我们提出了使用 罗伊氏利莫西乳杆菌 DSM20016的方案,详细介绍了生长、质粒转化、集落PCR、荧光报告蛋白测量和有限的质粒迷你制备,以及常见问题和故障排除。这些方案允许测量DSM20016中的报告蛋白,或者在没有报告基因的情况下 通过 集落PCR进行确认。

L.Reuteri,特别是菌株,DSM20016是一种健壮的、天然的人类肠道共生菌,在整个胃肠道中具有巨大的治疗递送和疾病检测前景。这项工作将有助于将DSM20016定位为这些应用的合成生物学底盘。乳酸杆菌没有特定的模式生物。

首选物种确实存在,但它们的选择通常偏向于特定的研究目标。细菌家族内的变异导致了碎片化的协议,其中一些协议的修改迭代可以追溯到出版物。对于刚开始的人来说,很难准确过滤什么是有用的,什么是没有用的。

确实存在一篇关于DSM20016转型的论文,但它不是现代的。存在其他乳酸杆菌家族成员的现代协议,但它们并不DSM20016。在这里,我们努力为DSM20016电穿孔提供一套易于使用、集中化、现代化、完整的实验方案。

与以前的DSM20016探索协议相比,该协议集提供了实质性的现代化,并阐明了一些悬而未决的线程,并强调了以前不太清晰的部分。该协议集也是完整的,专门针对DSM20016,其他非DSM20016协议并不完全兼容。我们的主要目标之一是使用微生物作为廉价的传感器和输送系统。

我们正在与肠道疾病专家合作,使用DSM20016来感知胃肠道的状况,并根据需要提供治疗。
