Visualization of mass cytometry cell signaling data from 14 cell types (y axis) identified in primary human peripheral blood mononuclear cells treated with 27 kinase inhibitors (x axis) and 14 stimuli (z axis). Bodenmiller et al. describe an approach for multiplexing samples for mass cytometry, which facilitates such largescale analyses (p 858). Credit: Erica Savig, Nolan Lab.
