Add more colors to multiple labeling assays in the UV/Vis region, with Brilliant Violet 421™ and Brilliant Violet 480™ conjugated secondary antibodies. When combined with Alexa Fluor® 488, Rhodamine-Red™-X, and Alexa Fluor® 647 conjugates, effective 5-color fluorescent labeling is possible.
If nuclear counterstaining is desired, 4-color antibody staining is possible using Brilliant Violet 421, Brilliant Violet 480, Alexa Fluor® 488 and Rhodamine Red™-X. Switching the nuclear stain from DAPI (emission in the blue region) to DRAQ5™ (which has red emission) frees the violet-blue region of the spectrum to accommodate the two Brilliant Violet dyes. DRAQ5’s excitation and emission profiles overlap those of Alexa Fluor® 647.
| Excitation Peak (nm) | Emission Peak (nm) | |
| Brilliant Violet 421™ | 407 | 421 |
| Brilliant Violet 480™ | 436 | 478 |
We offer a range of secondary antibodies that are recommended for multiple labeling due to their minimal cross reactivity, (See our multiple labeling guidelines for more information).

Excitation and Emission Spectra
Excitation and emission curves for BV 421™, BV 480™, Alexa Fluor ® 488, Rhodamine Red™-X, and Alexa Fluor® 657. DRAQ5 can be used as a nuclear stain in place of Alexa Fluor 647.
Brilliant Violet™ Dyes
BD Brilliant Violet polymer chains can be considered as a collection of optical segments, each with the ability to absorb light and emit fluorescence signal. This results in materials that have a bright fluorescence signal for better resolution and sensitivity.
Light harvesting base polymers have multiple optical segments that can emit for fluorescence detection.
