Immunophenotyping of human peripheral blood mononuclear cells by mass cytometry

Heck, S., Bishop, C.J. and Ellis, R.J.

Mass cytometry is a variation of conventional flow cytometry using metal tagged antibodies for cell staining instead of fluorochromes and detection in a mass cytometer, a modified mass spectrometer that allows for separation of discrete masses of these metal tags by time of flight (TOF). Currently, up to 50 different metal tags are available for cell analysis. The lack of any significant mass spectral overlap and autofluorescence background makes mass cytometry uniquely suited for complex high-dimensional phenotypic and functional analysis at the single cell level, thus accelerating biomarker discovery and drug screening. Here we describe a workflow for phenotyping of human peripheral blood mononuclear cells (PBMCs) covering cell staining, instrument setup of a Fluidigm Helios™ mass cytometer, and sample acquisition, and summarize a basic workflow of data analysis.
