SPY555-CA (SC206)

SPY555-CA is the ChloroAlkane (CA) derivative of our SPY555 fluorophore. It emits light in the orange part of the UV-ViS spectrum, it is fluorogenic, highly cell permeable and well suited for STED and SIM superresolution imaging. SPY555-CA can be imaged with a standard Cy3 filterset. It can be used for widefield, confocal, SIM or STED imaging in living or fixed cells and tissue. It has the same structure as MaP555-halo or MaP555-CA, the name used in its original publication in Nature Chemistry. 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. Contains 1 vial of SPY555-CA (lyophilized) *Halo-tag™ is a registered trademark of Promega Corporation.
