PURPOSE: This OMIP panel was designed to characterize the different subsets of human innate lymphoid cells (ILCs) including ILC1, ILC2, and ILC3 within healthy donors' cord blood (CB) (Table 1) in comparison to peripheral blood (PB). As ILCs represent a rare cell population in blood (0.1–0.5% of lymphocytes), the protocol was designed to rigorously exclude the contaminating cells with a complex lineage‐depleting antibody mixture (13 different antibodies) enabling analysis of highly pure ILC subsets by 8‐color staining.

CELL TYPE: Cryopreserved and freshly isolated cord blood and peripheral blood

MACHINE: Beckman Coulter CytoFLEX
