RayBright PE-Cy7

RayBright PE-Cy7 is a far red-emitting tandem fluorophore that combines phycoerythrin (PE) and Cy7. The donor molecule, PE can be excited by the 488-nm blue, 532-nm green, or 561-nm yellow-green laser and and transfers energy to the acceptor molecule, Cy7, which emits light that can be captured with a 780/60 nm bandpass filter. PE-CY7 has an excitation peak at 565 nm and an emission peak at 778 nm, and is a suitable alternative to PE-Vio®770 (Miltenyi) and cFluor BYG781 (Cytek).
