Selection Guide Fluorescent dye is a fluorescent chemical compound that can re-emit light upon laser excitation. Fluorophores typically contain several combined aromatic groups, or planar or cyclic molecules with several bonds. PEG spacers increase water solubility, enable efficient biolabeling in imaging and diagnostic R&D. Products: BP Light, BP Fluor, BODIPY, Cyanine 3, 5, 7, Fluorescein, Rhodamine, 800cw dye, and Pyrene dyes. Features: High water solubility, low non-specific binding, high S/N ratio. Note: Xenon arc lamp(250-1000nm) and Tungsten-halogen lamp(350-1000nm) are also used as light sources for all the dyes above. All the dyes below are arranged by max emission wavelength.
