CF®488A-cAMP and CF®640R-cAMP are fluorescently labeled cAMP analogs. Single molecules of fluorescently labeled cAMP have been imaged bound to the cAMP receptor on the surface of Dictyostelium cells (1).

Biotin-cAMP, diisopropylethylammonium salt is a biotin-conjugated cAMP analog that can be used to probe cAMP receptors.

Cyanine 644-cAMP is a fluorescently labeled cAMP analog and can be used to probe cAMP receptors. Single molecules of fluorescently labeled cAMP have been imaged as the probe binds to the receptor on the surface of Dictyostelium cells (1).
