Invitrogen Brilliant Ultra Violet™ 737 (BUV737) is a tandem dye excited by the 355 nm UV laser and emits at 737 nm far red. This dye has a medium-to-high relative brightness and can be used for cell surface, intracellular, and nuclear staining. BUV737 may have some cross-laser excitation with the blue and 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 using Super Bright Complete Staining Buffer or Brilliant Stain Buffer to minimize any non-specific polymer interactions.

We offer BUV737 dye conjugated to primary antibodies for use in flow cytometry.

Experimental data using Brilliant Ultra Violet™ 737

Spectral signature of Brilliant Ultra Violet™ 737 dye. Data acquired on a 5-laser Cytek Aurora and normal human peripheral blood cells stained with CD4 Monoclonal Antibody (RM4-5), Brilliant Ultra Violet™ 737 were used for analysis.

Dot plot of IFN-gamma-BUV737 vs CD4-PE in unstimulated and stimulated cells

Intracellular staining of mouse splenocytes using Brilliant Ultra Violet™ 737. C57BL/6 mouse splenocytes were stimulated for 72 hours with CD3e Monoclonal Antibody, Functional Grade and CD28 Monoclonal Antibody, Functional Grade. Cells were restimulated for 5 hours with Brefeldin A Solution (1000X) (left) or restimulated for 5 hours with Cell Stimulation Cocktail (500X) and Brefeldin A Solution (right). Cells were then stained intracellularly using the Intracellular Fixation & Permeabilization Buffer Set with CD4 Monoclonal Antibody, PE and 0.5 µg of IFN gamma Monoclonal Antibody, Brilliant Ultra Violet 737. Viable cells in the lymphocyte gate were used for analysis, as determined by LIVE/DEAD™ Fixable Violet Dead Cell Stain Kit, for 405 nm excitation.

Dot plots of samples stained with IgG1 control vs CD3-FITC and CD4-BUV737 vs CD3-FITC

Cell surface staining of human peripheral blood cells using Brilliant Ultra Violet™ 737. Normal human peripheral blood cells were stained with CD3 Monoclonal Antibody, FITC and Mouse IgG1 kappa Isotype Control, Brilliant Ultra Violet™ 737 (left) or CD4 Monoclonal Antibody, Brilliant Ultra Violet™ 737 (right). Viable cells in the lymphocyte gate were used for analysis, as determined by 7-AAD Viability Staining Solution.

Brilliant Ultra Violet™ dye background

Brilliant Ultra Violet dyes 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.
