Dissociation and flow cytometric isolation of murine intestinal epithelial cells for multi-omic profiling

Intestinal epithelium is composed of several cell types, which can be dissociated but difficult to maintain high cell viability due to anoikis. Herein, we describe a step-by-step protocol for the isolation of highly viable intestinal epithelial cells using ethylenediaminetetraacetate acid and TrypLE Express, which can subsequently be employed for multi-omic analyses, including single-cell RNA sequencing. For complete details on the use and execution of this protocol, please refer to Ge et al. (2022).¹.
