Fluorescence-activated cell sorting (FACS) offers these advantages: 

• Precise classification and analysis of cell subpopulations enabling researchers to isolate and collect cells with high specificity 
• Ability to differentiate the subtlest variations in cell phenotypes
• High-throughput capacity, facilitating the analysis and isolation of thousands of cells per second
• Enables simultaneous multi-parametric analysis, allowing researchers to simultaneously evaluate multiple characteristics of a single cell, which is crucial for understanding complex immune responses and diseases
