This video describes the procedure for snap freezing muscle tissue and obtaining its thin sections. The technique can help study cancer-related cachexia in colon cancer mouse models.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Muscle Freezing and Mounting Immerse the bottom half of a small plastic beaker (50 mL) containing isopentane into liquid nitrogen. The isopentane is ready to use when it becomes slightly viscous and forms a solid white laminate lining the inside of the beaker (temperature: -160 °C). NOTE: Al…
