ab134901 staining cAMP in SK-N-SH cells treated with (R)-(+)-Methanandamide (ethanol solution) (ab120361), by ICC/IF. Increase in cAMP expression correlates with increased concentration of (R)-(+)-Methanandamide (ethanol solution), as described in literature.The cells were incubated at 37°C for 10 minutes in media containing different concentrations of ab120361 ((R)-(+)-Methanandamide (ethanol solution)) 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 ab134901 (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.
