Deep Profiling of the Immune System of Multiple Myeloma Patients Using Cytometry by Time-of-Flight (CyTOF).

Mass cytometry has emerged as a new state-of-the-art technology that enables in-depth characterization of cellular populations and functions at a single cell resolution. We describe the application of this technology to deeply phenotype the blood and bone marrow components of multiple myeloma patients in a clinical setting. This technology allows for simultaneous quantification of more than 40 markers, overcoming the challenges of traditional fluorescence-based flow cytometry.
