NovaFluor dyes, including NovaFluor Yellow 755 dye, are built using Phiton technology and are compatible with both spectral flow cytometry and traditional flow cytometry. NovaFluor dyes exhibit narrow emission spectra and minimal cross-laser excitation, which helps reduce spectral spillover for better marker resolution. In addition, their unique spectral signatures can provide the opportunity to detect additional markers in flow cytometry panels by opening up previously unusable channels.
NovaFluor Yellow 755 dye has a unique emission spectrum when excited by the 561nm laser, which fits in a spectral space that is currently only accessible using cross-laser excited tandem dyes, such as PE-Cyanine7. Replacing highly cross-laser excited dyes may reduce spread, allowing for better resolution of low expressed markers. NovaFluor Yellow 755 dye should generally be paired with moderately expressed antigens to minimize spectral spillover in complex multicolor panels. The macromolecule-based NovaFluor Yellow 755 dye produces stable fluorescence, and stained samples retain their fluorescence intensity and spectral signature when stored at 4°C.
Benefits of NovaFluor Yellow 755 dye:
- Narrow emission spectrum and minimal cross-laser excitation for better resolution
- Should be paired with moderately expressed antigens to minimize spillover
- Can be used to replace cross-laser excited PE-Cyanine7
- Produces stable fluorescence and is compatible with all buffers tested
Use NovaFluor dyes with CellBlox Blocking Buffer to reduce background and to block non-specific binding of NovaFluor labels, PE and APC tandems observed with macrophages and monocytes.
