PE-Vio770

PE-Vio®770 (Ex-Max 565 nm/Em-Max 775 nm)

PE-Vio® 770 from Miltenyi Biotec is a red-emitting tandem fluorophore that combines pycoerythrin (PE) and Vio®770. 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, Vio®770, which emitts light that can be captured with a 780/60 nm bandpass filter. PE-Vio®770 has an excitation peak at 565 nm and an emission peak at 775 nm and is a common alternative to PE-Cy7 and PE-H7.
