ELISA Plot:. Adenosine-3', 5'-cyclic AMP immobilized onto plates, followed by addition of stand cyclic AMP. The mouse anti c-AMP was added subsequentially, and visiualized by chromatogenic substrate. Each sample was done in triplicate. IC50 was then calculated.

ICC/IF image of ab70280 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab70280, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

ab70280 staining cAMP in HEK293 cells treated with neuropeptide S (ab120174), by ICC/IF. Increase in cAMP expression correlates with increased concentration of neuropeptide S, as described in literature.The cells were incubated at 37°C for 10 minutes in media containing different concentrations of ab120174 (neuropeptide S) 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 ab70280 (5 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-mouse polyclonal antibody (ab96879) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.
