Phospho-specific flow: fixating on the target

Mark Levis. Clin Cancer Res. .

Abstract

Targeted therapies are all the rage in oncology research these days. The problem remains as to how to confirm that the target is actually being hit in vivo. This report describes the application of phospho-specific flow cytometry to establish in vivo target inhibition in real time.

Figure 1. Analyzing patient samples with phospho-specific flow
A small amount of a commercially-available fixative (formaldehyde-based) is added to a fresh blood sample. The sample can then be shipped to a central lab or processed immediately. After lysis of red blood cells permeabilization, the sample is incubated with antibodies to the phosphorylated targeted prior to analysis by flow cytometry.
