R-Phycoerythrin (R-PE)

Product Overview
Simply® R-PE is an intensely bright phycobiliprotein isolated from newly identified red algae species exclusive to coastal region of Taiwan. It exhibits extremely bright redorange fluorescence with high quantum yields.
With its broad range of excitation wavelengths, it can be easily excited by laser lines from 488 nm to 561 nm (blue, green, and yellow laser lines), with absorbance peaks at 499, 541, and 565 nm and a fluorescence emission peak at 581 nm.
