Description
The ex vivo addition of BD GolgiPlug™, a protein transport inhibitor containing brefeldin A, to in vitro- or in vivo-stimulated lymphoid cells blocks their intracellular protein transport processes. This results in the accumulation of cytokines and/or proteins in the Golgi complex. This increased accumulation of cytokines in the cell enhances the detectability of cytokine-producing cells with immunofluorescent staining and flow cytometric analysis.
