Commonly used methods to measure whole gut transit time in rodents have yet to combine high sensitivity, objectivity, and automation. We have developed a novel method using oral gavage of non‐toxic fluorescent dye particles and their detection by fluorescence imaging to enable unbiased automated detection of gut transit time simultaneously in 8 cages.

一种用于测量整个肠道通过时间的自动灵敏方法。

测量啮齿动物整个肠道通过时间的常用方法尚未结合高灵敏度、客观性和自动化。我们开发了一种新方法，使用口服管饲无毒荧光染料颗粒并通过荧光成像对其进行检测，从而能够在 8 个笼子中同时无偏地自动检测肠道通过时间。
