PB40-100- PerCP (Dinophyceae sp), 100 mg (formerly ProZyme). Peridinin-chlorophyll-protein complex (PerCP), is isolated from Dinophyceae sp. PerCP has an extremely high absorbance, a high quantum efficiency, a large Stokes shift, and a strong excitation peak at 482 nm with its maximum emission peak at 677 nm. The protein is commonly used for fluorescent immunolabeling, particularly in applications involving fluorescent activated cell sorting (FACS).
