Protocol for multi-organ isolation of murine leukocytes for flow cytometry.

ABSTRACT: The immune system comprises several specialized cells across multiple organs. Here, we present a protocol for the isolation of leukocytes from murine blood, spleen, mesenteric lymph nodes, liver, kidney, and skeletal muscle. We describe steps for cell isolation and gradient density separation and provide four antibody panels to identify adaptive immune cells (e.g., CD4⁺ and CD8⁺ T cell subsets) by flow cytometry. This protocol provides a basic framework for phenotyping immune cells from in vivo mouse models.
