BD566-CA (CY-SC220)

BD566-CA (also named BD566-HTL) is a ChloroAlkane (CA) derivative of the bridged-bicycle-strengthened orange fluorophore BD566. The unique BriDye™ bicyclic ether bridge technology1) confers to BD566-CA an exceptional photostability. It emits light in the orange part of the UV-ViS spectrum, it is highly cell permeable and well suited for superresolution imaging. BD566-CA absorption and emission maxima are 566 nm and 594 nm, respectively with an extinction coefficient of 108 000 M⁻¹ cm⁻¹ and a quantum yield of 0.85 (HT7 bound values). BD566-CA is highly cell-permeable, highly photostable, and compatible with standard Cy3 or TMR filter settings for widefield, confocal, SIM, or STED imaging in living or fixed specimens.
