PE-Cy5.5
PE-Cy5.5 (Ex-Max 565 nm/Em-Max 695 nm)
PE-Cyanine®5.5 (PE-Cy5.5) is a red-emitting tandem fluorophore that combines phycoerythrin (PE) and Cy5.5. 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, Cy5.5. PE-Cy5.5 has an excitation peak at 496 nm and an emission peak at 695 nm.
