Functional analysis of human circulating immune cells based on high-dimensional mass cytometry.

With the advantages of high resolution and high dimension, mass cytometry is implemented to analyze the blood complex immune system in clinical settings. However, long-term clinical sample collection may cause batch effects that mask true biological results. Here, we present a validated and streamlined mass cytometry workflow that features fixed staining for clinical use and optimized barcode staining patterns. The reagents and approaches used in this workflow can help reduce batch effects, thereby extending the application range and advantages of mass cytometry.
