Guidelines for Gating Flow Cytometry Data for Immunological Assays

Area of Science:

• Immunology
• Cell Biology
• Biotechnology

Background:

• Flow cytometry gating is crucial for analyzing cell subpopulations.
• Manual gating relies on expert knowledge but suffers from inter-observer variability.
• Existing guidelines are assay-specific, lacking comprehensive coverage for diverse immunological assays.

Purpose of the Study:

• To establish comprehensive guidelines for flow cytometry gating across various immunological assays.
• To address the lack of standardization in manual gating procedures.
• To improve the consistency and accuracy of cell subpopulation analysis.

Main Methods:

• Development of general gating guidelines based on common cell characteristics.
• Inclusion of example data from academic, government, and industry sources.
• Focus on fundamental gating strategies applicable to diverse immunological assays.

Main Results:

• Presentation of recommendations for the most common and critical gating strategies.
• Demonstration of gating principles using representative flow cytometry data.
• Consensus-based approach to guide gating practices.

Conclusions:

• Standardized flow cytometry gating guidelines are essential for reliable immunological assay results.
• These guidelines aim to reduce variability and enhance reproducibility in cell analysis.
• The recommendations are valuable for both novice and experienced researchers in flow cytometry.
