ABSTRACT
Here we describe the application of mass cytometry to analyze tumor-infiltrating lymphocytes in human melanoma. Mass cytometry is the coupling of flow cytometry and mass spectrometry, which allows for the simultaneous measurement of 40+ cell parameters on a per cell basis. Heavy metal-labeled antibodies can bind to proteins (CD markers, transcription factors, cytokines) on the cell surface and in the cytoplasm/nucleus. As labeled cells pass through the CyTOF, the instrument detects the heavy metals. Combining these signals allows description of melanoma tumor-infiltrating lymphocytes at a greater depth than alternative phenotyping strategies and enables detailed analyses of a variety of cellular parameters, including immune cell lineage, activation status, and functional polarization.
