Here, we present a protocol to use microfluidics in combination with fluorescence microscopy to expose the C. elegans tail to chemosensory stimuli. We describe steps for the preparation of microfluidic chips and sample preparation through the sedation of C. elegans. We detail flow calibration and imaging of C. elegans through fluorescence microscopy to determine their molecular and/or cellular response to chemosensory stimuli. This protocol can also be applied to amphid neurons by inserting the worm in the chip head-first. For complete details on the use and execution of this protocol, please refer to Bruggeman et al. (2022)..
在这里,我们提出了一个使用微流控技术结合荧光显微镜来使秀丽隐杆线虫尾部暴露于化学感觉刺激的方案。我们描述了微流控芯片的制备步骤和通过秀丽隐杆线虫镇静来进行样品制备的步骤。我们详细介绍了通过荧光显微镜对秀丽隐杆线虫进行流量校准和成像,以确定它们对化学感觉刺激的分子和/或细胞反应。通过将线虫头部插入芯片,本方案也可以应用于触角神经元。有关该方案使用和执行的完整详细信息,请参阅 Bruggeman 等人(2022 年)。
