This video demonstrates the assessment of chemical-induced colitis via immunohistochemical staining of mouse colon tissue. In a stained tissue section, the presence of a large number of immune-responsive cells in the damaged tissue represents the infiltration of immune cells during colitis.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Preparation of Mice and DSS Keep the knockout (α-gustducin-/-) mice and age-, gender-, and body weight-matched wild-type control (α-gustducin+/+) C57BL/6 mice individually in clean cages. NOTE: The knockout mice have been backcrossed with C57BL/6 mice for over 20 g…
