Quantitative Imaging of Lineage-specific Toll-like Receptor-mediated Signaling in Monocytes and Dendritic Cells from Small Samples of Human Blood

Overview

This article demonstrates the use of ImageStream technology to quantify cellular mechanisms of primary immune cells from well-defined patient cohorts. The process involves isolating peripheral blood mononuclear cells (PBMC) from blood samples, activating and labeling the cells, and then imaging them using a specialized cytometer.
