This video describes a simple and reliable method of introducing liquid into the trachea for lung instillation, fixation, and lung volume measurement.
Protocol
All procedures involving animals have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Lung Instillation Select a commercial one-inch long 20 g intravenous cannula to use for the intubation. Modify the catheter tip manually bending it to generate a slight curvature at the tip as illustrated in Figure 1. Anesthetize the mouse with a mixture of ketamine (100 mg/kg) and xylazin…
