Application Amino-reactive biolabel excited by red lasers (He/Ne; 633 nm) and diode lasers (635-650 nm). The chromophore is a bridged hemicyanine. Quantum yield is fairly low in aqueous media, but increases up to one order of magnitude if coupled to a target protein; Molar absorption 120,000 M-1 cm-1, λabs: (conjugate) 645 nm; λem: (conjugate) 660 nm Features and Benefits This novel hemocyanin dye is optimally excited by He-Ne laser with a wavelength of 633 nm, but may also be excited by argon or argon-krypton laser with a wavelength of 647 nm or diode lasers.Additional advantages are:High molar absorptions (120,000 M-1cm-1)Low quantum yields in nonaqueous media, greatly increased by binding to target molecules.Very strong fluorescence in solid state, which allows preparation of DNA for arrays on glass. |
