Abstract

Source: McManus, D. et al. Isolation of lamina propria mononuclear cells from murine colon using collagenase E. J. Vis. Exp. (2019)

In this video, we demonstrate the isolation of lamina propria mononuclear cells from murine colonic tissue by enzymatic digestion using collagenase E and silica-based density separation media gradient separation. The isolated mononuclear cells can be used for subsequent downstream analysis.

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 Solutions As described in Table 1, prepare the Colon Buffer, Silica-Based Density Separation Media 100%, Silica-Based Density Separation Media 66%, Silica-based Density Separation Media 44%, Collagenase E Digestion Buffer, and FACS Buffer. Prepare Colon Buffer the day prior to…
