CPY-CA (CY-SC306)

CPY-CA is the ChloroAlkane (CA) derivative of the fluorophore carbopyronin (CPY). It emits light in the red part of the UV-ViS spectrum, it is bright, highly cell permeable and well suited for STED and SIM superresolution imaging. CPY-CA can be imaged with 600/20 nm and 640/40 nm Abs/Em settings. It can be used for widefield, confocal, SIM or STED imaging in living or fixed cells and tissue. ChloroAlkane (CA) is the substrate of the self labeling tag Halo-tag™*. Upon reaction with a CA derivative, Halo-tag™* forms a covalent bond with the substrate. It allows to permanently attach a fluorescent label to any protein of interest (POI) expressed as Halo-tag™* fusion. Probe Properties
