Brilliant Violet™ dyes, including Brilliant Violet™ 605 (BV605), are a polymer dye-based technology and compatible with both spectral flow cytometry, as well as traditional flow cytometry. The violet laser has unique channels far from heavily occupied detectors allowing for larger panels.

BV605 is a tandem dye excited by the 405 nm violet laser and emits at 605 nm. This dye has a medium-high relative brightness and can be used for cell surface, intracellular, and nuclear staining.

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.
