High-parameter T-cell spectral phospho-flow-cytometry.

Area of Science:

• Immunology
• Cellular Signaling
• Flow Cytometry

Background:

• Phospho-flow cytometry is crucial for studying immunological signaling, enabling simultaneous detection of cell markers and intracellular phospho-proteins.
• It has potential applications in diagnostics, therapeutics, drug screening, and efficacy assessment.
• Fluorescent cell barcoding (FCB) enhances flow cytometry throughput and experiment robustness.

Purpose of the Study:

• To describe a standardized experimental method for stimulating mouse and human T cells.
• To address inter-operator variability in phospho-flow assays.
• To provide a adaptable protocol for robust T cell activation.

Main Methods:

• Development of a standardized T cell stimulation protocol.
• Integration of phospho-flow with fluorescent cell barcoding (FCB) for multiplexing.
• Application to mouse and human T cell activation studies.

Main Results:

• Demonstration of robust T cell activation using the described method.
• Improved experimental consistency and reduced variability in flow cytometry staining.
• Successful adaptation for diverse experimental designs.

Conclusions:

• The presented method provides a standardized approach to T cell stimulation for phospho-flow analysis.
• This standardization enhances reproducibility and reduces variability in immunological signaling studies.
• The adaptable protocol supports high-throughput flow cytometry applications.
