NovaFluor Red 685 dye

NovaFluor dyes, including NovaFluor Red 685 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 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 Red 685 dye is ~4 times brighter than APC-Cyanine 5.5 and Alexa Fluor 680 dye. In complex multicolor flow cytometry panels, NovaFluor Red 685 dye can be used to fill the spectral gap between Alexa Fluor 647 and Alexa Fluor 700 dyes. The macromolecule-based NovaFluor Red 685 dye produces highly stable fluorescence, and stained samples retain their fluorescence intensity and spectral signature when stored at 4°C.

Benefits of NovaFluor Red 685 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 be used to fill the spectra gap between Alexa Fluor 647 and Alexa Fluor 700 dyes
  • Can be used in a flow cytometry panel with NovaFluor Red 660 (or APC-Alexa Fluor 647) and Alexa Fluor 700 dyes
  • 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.
