Invitrogen NovaFluor Yellow 570 dye can be used as an alternative to phycoerythrin (PE) with similar emission spectrum but far less cross-laser excitation by the blue 488 nm laser. NovaFluor Yellow 570 dye should generally be paired with highly expressed antigens to minimize spectral spillover in complex multicolor panels.

The macromolecule-based NovaFluor Yellow 570 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.

We offer NovaFluor dyes conjugated to primary antibodies for use in flow cytometry, as well as NovaFluor Antibody Conjugation Kits, NovaFluor CD4 Label Characterization Kits, and custom conjugation services.

  • Can serve as a replacement for PE with far less cross-laser excitation
  • Produces highly stable fluorescence and is compatible with all buffers tested
Experimental data using NovaFluor Yellow 570 dye

Spectral signature of NovaFluor Yellow 570 dye. Normal human peripheral blood cells stained with CD4 Monoclonal Antibody (SK3 (SK-3)), NovaFluor Yellow 570 were used for analysis. Data was acquired on a 5-laser Cytek Aurora system.

2-panel scatter plots of mouse splencoytes, unstained vs. CD3e-stained and CD19-stained vs. CD3e-stained
Staining of mouse splenocytes with NovaFluor Yellow 570 conjugated antibody. C57BL/6 mouse splenocytes were unstained (left) or stained with 0.2 µg of CD19 Monoclonal Antibody, NovaFluor Yellow 570 (right). All cells were co-stained with CD3e Monoclonal Antibody, eFluor 450. Total viable cells in the lymphocyte gate were used for analysis, as determined by LIVE/DEAD Fixable Blue Dead Cell Stain Kit, for UV excitation. Data was acquired on a 5-laser Cytek Aurora and unmixed with autofluorescence extraction.
