NovaFluor Yellow 730 dye

NovaFluor dyes, including NovaFluor Yellow 730 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, reducing spectral interference 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 730 dye can be used as an alternative to PE-Cyanine 5.5, with far less cross-laser excitation and spectral spillover. NovaFluor Yellow 690, NovaFluor Yellow 700 and NovaFluor 730 dyes cannot be used together with conventional flow cytometry, but their distinct spectral signatures allow them to be successfully unmixed using a spectral flow cytometer. The macromolecule-based NovaFluor Yellow 700 dye produces highly stable fluorescence, and stained samples retain their fluorescence intensity and spectral signature when stored at 4°C.

Benefits of NovaFluor Yellow 730 dye

  • Narrow emission spectrum and minimal cross-laser excitation for better resolution
  • Bright fluorescence allows it to be paired with medium-to-low abundance antigens
  • Can serve as a replacement for PE-Cy5.5, with far less cross-laser excitation and spectral spillover
  • Can be used together with NovaFluor Yellow 690 and NovaFluor Yellow 700 using a spectral flow cytometer
  • Produces highly stable fluorescence and is compatible with all buffers tested

Use NovaFluor dyes with CellBlox Monocyte and Macrophage Blocking Buffer to block non-specific binding of NovaFluor labels, PE and APC tandems observed with macrophages and monocytes.
