Abstract
Source: Baxter, R. M., et al. Single-cell Analysis of Immunophenotype and Cytokine Production in Peripheral Whole Blood via Mass Cytometry. J. Vis. Exp. (2018).
This video highlights a single-cell proteomic method that employs heavy-metal-conjugated antibodies for distinct cell barcoding. Subsequently, immunostaining and mass cytometry are applied to evaluate immune phenotypic and functional alterations in human whole blood-derived immune cells.
Protocol
1. Barcode of Lysed/Fixed Blood Cells Thaw the lysed/fixed cell samples from the -80 °C storage slowly on ice; a maximum of 20 samples can be labeled with unique barcodes and pooled using this system. Dilute the 10X barcoding perm buffer by 1:10 with PBS; make enough buffer for ~3 mL per sample. Fill one non-sterile trough with the CSM and one with the 1X barcoding perm buffer. Add 1 mL of ice-cold CSM to freshly thawed samples, mix thoroughly with a pipette, and transfer to th…
