Analysis of signaling events by dynamic phosphoflow cytometry.

Abstract excerpt

Many proteins involved in cell signaling are phosphorylated. To determine the phosphorylation status of these signaling molecules at the single-cell level, we present a protocol for using state-specific antibodies to detect target phosphoproteins with fluorescence measurements by flow cytometry. To improve the signal intensity, a sandwich-labeling method for the analysis of signaling proteins is performed. By...
