Cytometry by time‐of‐flight (CyTOF)


Course Goals 

The course will comprise theory and practice of mass-cytometry applied to assessing the immune response in human and animal models. Cytometry by time‐of‐flight (CyTOF), or mass cytometry, allows the simultaneous detection of multiple phenotypic markers at the single cell level by making use of antibodies and specific probes conjugated with pure heavy metal isotopes. Labelled cells are then detected by atomic mass spectrometry. Whereas most conventional flow cytometry can be used to measure fluorescence in a maximum of 18 channels, with considerable spectral overlap requiring ad hoc mathematical processing, CyTOF technology makes it possible to measure more than 50 different parameters (in theory 130), with minimal spectral overlap. The course will describe the technology in details, and will present methods for characterizing surface markers and intracellular markers (cytokines and degranulation markers), allowing the characterization of activation, differentiation and functionality of lymphoid and myeloid cells. The training will be particular focused on new methods for unsupervised analysis of high dimensional data generated by flow and mass cytometry.
