SiR-CA (SC506)

SiR-CA is the ChloroAlkane (CA) derivative of our SiR fluorophore. It emits light in the far red part of the UV-ViS spectrum, it is fluorogenic, highly cell permeable and well suited for STED and SIM superresolution imaging. SiR-CA can be imaged with a standard Cy5 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 SiR-Halo, 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 SiR-CA (lyophilized). *Halo-tag™ is a registered trademark of Promega Corporation.
