PerCP (Peridinin-Chlorophyll-Protein Complex)

PerCP (Peridinin-chlorophyll-protein complex) is isolated from Dinophyceae sp. It has a high quantum efficiency and a large Stokes shift. It is well excited at 488 nm with its maximum emission peak at 677nm. PerCP protein is commonly used for fluorescent immunolabeling, particularly in applications involving fluorescent-activated cell sorting. Its cyanine tandem conjugates (such as PerCP-Cy5.5) can be excited with a standard 488 nm laser and emits in the far red at a longer wavelength for multicolor flow cytometric analysis of cells. These multiple emission wavelengths make PerCP- Cyanine conjugates potentially useful fluorochromes for multicolor analysis. Molecular Weight: 35 kDa Absorption Maximum: 477 nm Emission Maximum: 678 nm Formulation: Protein solution in 50 mM HEPES pH 7.5 with 15 mM sodium azide. Extinction Coefficient: 4.06×105cm-1M-1
