The document describes 11 fluorescent dyes that emit between 670-770 nm. It provides information on the dyes' code, absorption and emission wavelengths, molecular weight, purity, extinction coefficient, quantum yield, chemical description, and available forms. The dyes are pentamethine or heptamethine cyanine dyes that are either symmetric or asymmetric and contain one positive or negative charge. They are available as free acids, NHS esters, maleimides, sulfonated or hydroxyl forms.
