WebAbstract. The analysis of heterogeneous cell samples by mass cytometry (CyTOF) relies on the assumption that metal labeled antibodies accurately bind to their target antigens. We report a previously unappreciated experimental artifact of non-specific antibody binding by eosinophils during intracellular CyTOF analysis of human whole blood samples. WebIf the non-specific binding were mediated by Fc binding, the Fc blocker (Human TruStain FcX™) alone would have fixed the problem. In instances where only the antibody exhibiting non-specific binding (for example, CD3 APC/Cy7, CD56 PE/Cy5 and CD19 PE/Dazzle™ 594) was used to costain cells with CD14 BV421™, the True-Stain Monocyte Blocker ...
