PBMC: Normal Human Peripheral Blood Mononuclear Cells (PBMCs)

In cytolab/cytoMEM: Marker Enrichment Modeling (MEM)

Normal Human Peripheral Blood Mononuclear Cells (PBMCs)

Description

This dataset contains 49651 events from a 25-marker panel CyTOF analysis of normal human PBMCs. Expression values are the raw (pre-transformation) median intensity (MI) values.

Data has been pre-gated to include only DNA-intercalator (Iridium) positive and CD45-high events. Expert biaxial gating was used to separate these events into 7 major blood cell populations: CD4+ T cells (cluster 1), CD8+ T cells (cluster 2), IgM+ B cells (cluster 5), IgM- B cells (cluster 4), dendritic cells (DCs) (cluster 3), natural killer (NK) cells (cluster 7), and monocytes (cluster 6). Per-cell population identity is specified in the cluster channel (variable).

This dataset is meant to be used as an example with the MEM package.

See refs for experimental protocol and further details.
