An improved protocol to isolate enriched immune cells from murine intestinal epithelium and lamina propria

The intestine is home to more immune cells than any other non-lymphatic peripheral tissue, but research of these cells is stymied by the technical difficulties involved in isolating them. Here, we describe a protocol to isolate highly viable immune cells from murine intestinal epithelium and lamina propria. This protocol can be used to characterize cells by flow cytometry or single-cell transcriptomics, as in Crotts et al., or by other analysis methods.
