We present a high-throughput flow cytometric assay to determine the phagocytic activity of antigen-specific antibodies from clinical samples, utilizing fluorescent antigen-coated beads and a monocytic cell line expressing multiple Fc receptors—providing receptor usage and phagocytic activity determinations in a standardized and reproducible fashion for any antigen of interest.
