Product introduction： DyLight Long Stokes Shift Specialty Dyes have fluorescence emission from green to far red with a single excitation peak that matches the 488 laser line and very large Stokes shifts that inhibit quenching. DyLight 515-LS dye has excitation and emission peaks at 519 and 648 nm, respectively. DyLight Long Stokes Shift Specialty Dyes are a family of labeling agents that provide bright fluorescent detection for multiplexed imaging. The dyes share a common excitation range, while their emission properties extend from the green to the far red wavelengths. The dyes are based on a core coumarin structure that is modified to emit at different wavelengths. Each dye contains an amine-reactive NHS ester for rapid modification of antibodies, proteins, peptides or other biomolecules through amide bond formation. DyLight Long Stokes Shift Dyes can be used individually or combined with DyLight 488 for multiplexed analysis. The excitation and emission peaks are sufficiently separated so as to minimize dye-dye quenching in assays. General features of the DyLight Long Stokes Shift Specialty Dyes: • Single excitation wavelength—DyLight Long Stokes Shift Dyes all can be excited together at 488 nm using an Argon laser • Image multiple targets simultaneously—the four Long Stokes Shift Dyes can be used with DyLight 488 for multiplex fluorescence applications • NHS ester reactive group—allows immediate labeling of antibodies, proteins, peptides and other amine-containing molecules through amide bond formation • Multiple solubility options—choose from hydrophilic to hydrophobic dyes to optimize the right dye label for the best performance in an application • Large Stokes shift inhibits quenching—minimal overlap between excitation and emission peaks inhibits dye-dye quenching effects • Use in FRET-based assays—the extremely broad separation between excitation and emission peaks allow for use of the Long Stokes Shift Dyes in energy transfer applications where the acceptor dye is spectrally far removed from the excitation wavelength. Criteria to consider when choosing a DyLight Long Stokes Shift Specialty Dye: • Excitation and emission wavelengths—all dyes share a common excitation wavelength range with options for emission from the green to the far red wavelengths. • Water solubility—DyLight Long Stokes Shift Dyes can be initially solubilized in methanol, ethanol, DMF or DMSO with transfer into an aqueous buffer medium for labeling biomolecules Applications: • Quenchers and FRET pairs • Conjugation to silica particles • STED microscopy • Multicolor microscopy • 4Pi microscopy • Dual-color 3D nanoscopy • Dynamic light scattering • Graded stokes shift • Duplex enhanced RT-PCR • High-resolution optical microscopy |
