NovaFluor Blue 800 dye has a unique emission spectrum when excited by the 488 nm laser, which fits in a spectral space that is currently not accessible by other spectral dyes. Additionally, its narrow excitation spectrum can be paired with that of NovaFluor Yellow 810 dye to replace the broad excitation spectrum of PE/Fire 810 dye. Adding spectrally unique dyes may allow for building out larger panels with minimal loss of resolution. NovaFluor Blue 800 dye should generally be paired with moderately to highly expressed antigens in multicolor panels. The macromolecule-based NovaFluor Blue 800 dye produces highly stable fluorescence, and stained samples retain their fluorescence intensity and spectral signature when stored at 4°C. Use NovaFluor dyes with CellBlox Plus Blocking Buffer to reduce background and to block non-specific binding of NovaFluor labels, PE and APC tandems observed with macrophages and monocytes.

Figure 2. NovaFluor Blue 800 dye can be paired with NovaFluor Yellow 810 dye while providing resolution and low spillover spread. Human PBMC were stained with CD27 NovaFluor Blue 800 dye and CD8 NovaFluor Yellow 810 dye. Viable cells were used for analysis, as determined by LIVE/DEAD Fixable Blue Dead Cell Stain Kit (Cat. No. L34962). Data was collected on a 5-laser Cytek Aurora Flow Cytometer.
NovaFluor Blue 800 dye background
NovaFluor dyes, including NovaFluor Blue 800 dye, are built using Phiton technology and are compatible with both spectral flow cytometry and traditional flow cytometry. NovaFluor dyes exhibit narrow excitation 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.
