Macrophage Isolation from the Mouse Small and Large Intestine

Macrophages play important roles in maintaining intestinal homeostasis via their ability to orchestrate responses to the normal microbiota as well as pathogens. One of the most important steps in beginning to understand the functions of these cells is the ability to effectively isolate them from the complex intestinal environment. Here, we detail methodology for the isolation and phenotypic characterization of macrophages from the mouse small and large intestine.
