Spectraviewer image of Brilliant Ultra Violet 661 dye

Brilliant Ultra Violet™ dyes, including Brilliant Ultra Violet™ 661 (BUV661) dye, are a polymer dye-based technology and compatible with both spectral flow cytometry, as well as traditional flow cytometry. The UV laser has unique channels far from heavily occupied detectors allowing for larger panels.

BUV661 is a tandem dye excited by the 355 nm UV laser and emits at nm. This dye has a medium-to-high relative brightness and can be used for cell surface, intracellular, and nuclear staining. BUV661 may have some cross-laser excitation with the red laser.

When using two or more Super Bright, Brilliant Violet, Brilliant Ultra Violet™, or other polymer dye- conjugated antibodies in a staining panel, we recommend that you use Super Bright Complete Staining Buffer (Cat. No. SB-4401-42) or Brilliant Stain Buffer (Cat. No. 00-4409-42) to minimize any non- specific polymer interactions.

Experimental data using BUV661 dye products

Figure 1. Excitation and emission of Brilliant Ultra Violet™ 661 dye (BUV661).

Figure 2. Spectral signature of BUV661 dye. Data acquired on a 5-laser Cytek Aurora and normal human peripheral blood cells stained with clone SK7 (hCD3) conjugated to BUV661 dye (Cat. No. 376-0036-42) were used for analysis.

Figure 3. C57BL/6 mouse splenocytes were unstimulated (left) or stimulated for 48 hours with CD3e Monoclonal Antibody, Functional Grade (Cat. No. 16-0031-85) (right). Cells were then stained intracellularly, using the Foxp3/Transcription Factor Staining Buffer Set (Cat. No. 00-5523-00) and protocol, with CD45R (B220) Monoclonal Antibody, FITC (Cat. No. 11-0452-82) and 1.0 µg of Ki-67 Monoclonal Antibody, Brilliant Ultra Violet™ 661 dye (Cat. No. 376-5698-82). Viable cells in the lymphocyte gate were used for analysis, as determined by LIVE/DEAD™ Fixable Blue Dead Cell Stain Kit (Cat. No. L34962).

Figure 4. C57BL/6 mouse splenocytes were stained with CD3e Monoclonal Antibody, FITC (Cat. No. 11-0031-82) and 0.25 µg of Rat IgG2a kappa Isotype Control, Brilliant Ultra Violet™ 661 dye (Cat. No. 376-4321-81) (left) or 0.25 µg of CD4 Monoclonal Antibody, Brilliant Ultra Violet™ 661 dye (Cat. No. 376-0042-82) (right). Viable cells in the lymphocyte gate were used for analysis, as determined by 7-AAD (Cat. No. 00-6993-50).
