Comprehensive immune cell profiling by CyTOF using blood obtained by capillary self-sampling device vs venipuncture and finger-prick blood draw methods

To compare immune profiles from blood drawn using traditional venipuncture vs capillary finger-prick vs a nearly painless capillary self-sampling TAP-device by mass cytometry Conclusion: We show using Mass cytometry that system-level immune cell profiles are comparable to traditional sampling via venipuncture and that blood volumes are enough to capture global immune system states Panel has been tested on cells obtained from fixed/lysed blood (fixed using Cytodelics whole blood processing kit) of a healthy donor
