製品の詳細Inhibitor of ADP-ribosylation factor
生理活性の詳細Reversible inhibitor of protein translocation from the endoplasmic reticulum to the Golgi apparatus. Inhibits binding of the cytosolic coat protein, β-COP and ADP-ribosylation factor (ARF) to Golgi membranes and inhibits GDP-GTP exchange.
保存方法Store at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
溶解性Soluble in DMSO to 50 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

ab84340 staining golgin-97 in MCF7 cells treated with brefeldin A (ab120299), by ICC/IF. Increase in Golgin-97 expression correlates with increased concentration of brefeldin A, as described in literature.
The cells were incubated at 37°C for 1.5 h in media containing different concentrations of ab120299 (brefeldin A) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab84340 (5 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.
