An Imaging Flow Cytometry Protocol for Studying Immunoregulatory Receptor-Mediated Regulation of Phagocytosis.

Advances in flow cytometry have allowed for innovative functional investigations of innate immune cell responses. Imaging flow cytometers combine the imaging capabilities of microscopy with rapid, high-throughput data acquisition attributes of standard flow cytometers. Here, we describe a detailed method for co-expressing stimulatory and inhibitory immunoregulatory receptor-types in AD293 cells and then measuring receptor cross-talk during the regulation of the phagocytic response. Information on reagent selection, imaging flow cytometry calibration, and automated template analyses are included.
