NovaFluor UV 765 dye has a unique emission spectrum when excited by the 349 nm laser, which fits in a spectral space that is currently not accessible by other spectral dyes. Adding spectrally unique dyes may allow for building out larger panels with minimal loss of resolution. NovaFluor UV 765 dye should generally be paired with moderately to highly expressed antigens in multicolor panels. The macromolecule-based NovaFluor UV 765 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.

NovaFluor UV 765 primary antibodies

  • Narrow emission spectrum and minimal cross-laser excitation for better resolution
  • Should be paired with moderately expressed antigens to minimize spillover
  • Spectrally unique and can be used to fill unused detectors in conventional flow cytometry
  • Produces stable fluorescence and is compatible with all buffers tested

Figure 2. NovaFluor UV 765 dye is compatible with spectrally adjacent fluorophores, BUV615, BUV661, BUV737, and BUV805, in the same experiment. Human PBMC were stained with CD3 Brilliant Ultra Violet 737 dye (left), CD4 NovaFluor UV 765 dye, CD8 Brilliant Ultra Violet 805 dye (middle), CD45RA Brilliant Ultra Violet 661 dye, and CD27 Brilliant Ultra Violet 615 dye (right). The CD3-positive gate was used for analysis in the middle and right plots. 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 UV 765 dye background

NovaFluor dyes, including NovaFluor UV 765 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.
