Phagocytosis Functional Assay
A phagocytosis functional assay measures the ability of phagocytic cells, such as neutrophils, macrophages, monocytes, or microglia/macrophages, to bind and internalize particulate targets including bacteria, yeast particles, beads, or myelin particles. Fluorescent flow-cytometry assays detect target uptake as fluorescence associated with gated phagocytes, while pH-sensitive dyes such as pHrodo increase signal in acidic phagosomal compartments and therefore preferentially report internalized particles rather than particles remaining outside the cell. Microscopy or high-content imaging can be used to confirm intracellular localization and, in some protocols, to follow uptake kinetics.
