Explore our broad portfolio of high-quality dyes and conjugates that can help expand your experimental design options. To power our BD FACSymphony™ family of instruments to do high-parameter flow cytometry, we offer small-scale conjugations between virtually any dye and any clone in our catalog. We also offer access to prototype dyes that are exclusive to BD, and we can conjugate our dyes to customer-provided materials. 




Custom Conjugates

The BD catalog contains over 18,000 unique antibody-dye combinations for flow cytometry, including the BD Horizon Brilliant™ Reagents. However, we know that your research sometimes requires a unique combination that is not readily available. The BD customs program can provide any conjugation you need within our portfolio of fluorescent dyes and antibodies, with all the same configurable specifications.


Are you developing your own antibodies in house or sourcing antibody content that BD does not have? Send us your antibodies! BD Biosciences will conjugate your antibodies to our wide array of fluorochromes, including our BD Horizon Brilliant™ Dyes.*

Prototypes of BD Horizon Brilliant™ Dyes (-P)

BD Life Sciences is committed to continuing to develop new BD Horizon Brilliant™ Dyes across various laser lines to improve the spectral properties of dyes and minimize the need for compensation in higher-order panels.


These prototype (-P) dyes have reached initial quality specifications but may undergo additional development that could result in minor performance changes. Any significant changes to the structure of the dye to optimize performance will be appropriately communicated to customers.
