Storage instructionsStore at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in water
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 week. 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.

ab6427 staining dopamine in PC12 cells treated with ghrelin (rat) (ab120231), by ICC/IF. Decrease in dopamine expression correlates with increased concentration of ghrelin, as described in literature.
The cells were incubated at 37°C for 10 minutes in media containing different concentrations of ab120231 (ghrelin) in DMSO, fixed with 100% methanol for 5 minutes at -20°C 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 ab6427 (1/200 dilution) 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.
