Insights

We developed four high-parameter flow cytometry panels for deep immunophenotyping of human peripheral blood mononuclear cells (PBMC). These panels enable comprehensive immune cell analysis across different lineages and activation states.

Area of Science:

  • Immunology
  • Cell Biology
  • Biotechnology

Background:

  • High-dimensional flow cytometry is crucial for multi-omic studies of the human immune system.
  • Deep immunophenotyping requires robust and comprehensive cell surface marker panels.

Purpose of the Study:

  • To present four high-parameter flow cytometry panels for deep immunophenotyping of human peripheral blood mononuclear cells (PBMC).
  • To provide guidelines for designing flow cytometry experiments for immune profiling.

Main Methods:

  • Development of four 25+ color flow cytometry panels targeting 64 cell surface markers.
  • Integration of common lineage bridging markers for inter-panel quality control.
  • Validation of panels on both BD Symphony A5 and Cytek Aurora cytometers using nine PBMC samples.

Main Results:

  • The four panels enabled deep immunophenotyping of T, B, NK, and myeloid lineages, including activation and memory states.
  • Comparable high-quality data were obtained from both conventional and spectral cytometers.
  • The panels demonstrated suitability for longitudinal or cross-sectional immune profiling.

Conclusions:

  • The presented modular panel set and instrument performance metrics offer a valuable resource for researchers in human immunology.
  • These panels facilitate standardized and reproducible deep immunophenotyping of PBMCs.
  • The findings support the use of spectral cytometry for high-dimensional immune profiling.
