direct tracheal instillation of solutes into mouse lung

气管内灌注，直接传送到肺部的溶质。此过程中的目标进入肺远端地区instillate交付，因此，往往在研究旨在研究肺泡中。我们提供一个详细的生存协议执行在老鼠的气管内灌注。使用这种方法，可以进入远端肺目标提供测试溶质或固体（如肺癌治疗，表面活性剂，病毒，和小寡核苷酸）。气管灌注可能是首选的方法，对吸入协议可能主要目标和上呼吸道有可能使潜在的有害物质的调查。此外，在使用气管滴入协议中，动物可以完全恢复从非侵入性的程序。这使得随后的实验动物，或重新安装使用相同的动物的生理测量。进入肺部介绍instillate必须审慎考虑后，决定和渗透平衡，以确保动物恢复。通常情况下，30-75μL的instillate体积可以被引入到小鼠肺。
