BD GolgiStop™ Protein Transport Inhibitor (Containing Monensin)

(RUO)
Product Details
Down Arrow Up Arrow


Description

The ex vivo addition of BD GolgiStop™, a protein transport inhibitor containing monensin, 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. The increased accumulation of cytokines in the cell enhances the detectability of cytokine-producing cells with flow cytometric analysis.

Investigators should note that the appearance of BD GolgiStop™ may range in color from clear (colorless) to a light yellow.



Recommended Assay Procedures

Stimulation of Cells:  Various in vitro methods have been reported for stimulating cells to produce cytokines. Polyclonal activators have been particularly useful for inducing cytokine-producing cells. These activators include the following: concanavalin A, lipopolysaccharide, phorbol esters plus calcium ionophore or ionomycin, phytohaemaglutinin, staphlylococcus, entertoxin B, and monoclonal antibodies directed against subunits of the TCR/CD3 complex (with or without antibodies directed against costimulatory receptors, such as CD28).

Procedure for Using BD GolgiStop™:  Add 4 µl of BD GolgiStop™ for every 6 mL of cell culture (e.g., ~10^6 cells/mL) and mix thoroughly. Treatment of stimulated cells for 4 to 6 hours with BD GolgiStop™ significantly increases the ability to detect cytokine-producing cells by immunofluorescent staining. It is recommended that BD GolgiStop™ not be kept in cell culture for longer than 12 hours.

As an alternative to BD GolgiStop™, investigators may wish to use BD GolgiPlug™ , a protein transport inhibitor containing brefeldin A (Cat. No. 555029).  BD GolgiStop™ and BD GolgiPlug™ have been found to have differential effects on intracellular cytokine staining that is time, activator and cytokine dependent. These factors must be considered when carrying out intracellular staining.

Danger:  BD GolgiStop™ Protein Transport Inhibitor, containing monensin (component 51-2092KZ) contains 99.61% ethanol (w/w) and 0.26% monensin, mononatriumsalz (w/w).
