Brefeldin A is an inhibitor of intracellular protein transport. Incubation of cells in culture with Brefeldin A leads to blockade of protein transport to the Golgi complex (GC) and accumulation of proteins in the endoplasmic reticulum (ER). Addition of Brefeldin A during the last hours of in vitro activation of cells results in enhanced detection of intracellular cytokines. Brefeldin A is effective for enhanced detection of a majority of mouse and human intracellular cytokines; however, it is advised that the investigators evaluate the use and efficacy of this reagent as well as other protein transport inhibitors such as Monensin in their specific assay system.
The Brefeldin A Solution is supplied at 1000X working concentration in methanol. Prior to addition to the cell cultures, a 1:1000 dilution in the culture media should be made. The final working concentration of the Brefeldin A (at 1x) is 3.0 ug/ml.
