xtraFluor™ Violet 420 Streptavidin Conjugate
xtraFluor™ Violet 420 Streptavidin Conjugate is an exceptionally bright violet laser-excitable conjugate that delivers superior signal intensity for detecting biotinylated molecules in multicolor flow cytometry panels.
  • Spectral profile: Ex/Em ≈ 405/420 nm; optimized for the 405 nm violet laser
  • Superior Dim Population Resolution: Brighter than Pacific Blue™ and BD Horizon™ V450, direct spectral match to BV421™
  • Enhanced Stability Profile: Resists photobleaching and maintains fluorescence in standard buffers
  • Steptavidin-tagged: Detects biotin-labeled molecules such as biotinylated antibodies, pepties, and oligonucleotides
Top)The spectral profile was acquired using a 4-laser spectral flow cytometer equipped with spatially offset excitation sources at 355 nm, 405 nm, 488 nm, and 640 nm. Each laser produced a distinct emission pattern, and the combined emission spectra were used to generate the composite spectral signature. Bottom) Flow cytometric analysis of human whole blood cells stained with biotinylated anti-CD4 antibody (0.5 µg/test), followed by detection with xtraFluor™ Violet 420-streptavidin (0.25 µg/test). Fluorescence was measured using the V1-A detector channel on the Aurora spectral cytometer.
