Here, we present a protocol for identifying human innate lymphoid cells (ILCs) and T cells using a 19-plex flow cytometry panel. We describe steps for titrating antibodies, preparing single-stain controls and samples, and staining cells for human peripheral blood and bone marrow samples. We then detail procedures for transferring a flow cytometry panel optimized for conventional cytometry to spectral flow cytometry analysis. This protocol facilitates correlation with murine models, maximizes measurable parameters, resolves complex fluorophore combinations, and increases panel flexibility.
