Image-based Flow Cytometry Technique to Evaluate Changes in Granulocyte Function In Vitro

Overview

This method demonstrates a technique for assessing granulocyte function by simultaneously measuring phagocytosis of bacteria and oxidative burst. Image-based flow cytometry allowed for the identification of three distinct subsets of activated granulocytes that all differed in their relative functional capacity.
