PTPRC and neoplasm: When using sample barcoding, updating the CyTOF® software with separate labels for all barcodes is strongly recommended throughout the sample run [e.g., for CD45 live barcoding, rather than a uniform label of “CD45”, it is preferable to use “CD45_102” (isotope mass), “CD45_healthy” (experimental group), or “CD45_tumor” (tissue type)].
