Spectraviewer image of NovaFluor Blue 690 dye

NovaFluor dyes, including NovaFluor Blue 690 dye, are built using Phiton technology and are compatible with both spectral flow cytometry as well as 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 Blue 690 dye has a unique emission spectrum when excited by the 488nm laser, which fits in a spectral space that is currently only accessible using cross-laser excited tandem dyes, such as PerCP-Cyanine5.5. Replacing highly cross-laser excited dyes may potentially allow for the inclusion of an additional marker in a complex multicolor panel. NovaFluor Blue 690 dye should generally be paired with retain their fluorescence intensity and spectral signature when stored at 4°C.

Benefits of NovaFluor Blue 690 dye:

  • Narrow emission spectrum and minimal cross-laser excitation for better resolution
  • Should be paired with highly expressed antigens to minimize spillover
  • Can be used to replace cross-laser excited PerCP-Cyanine5.5
  • Produces highly 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.
