Bio-Rad Laboratories StarBright Violet 515 Dye for Flow Cytometry

Bio-Rad Laboratories has launched the StarBright Violet 515 (SBV515) dye, the first of a new range of fluorescent nanoparticles for flow cytometry. SBV515 has an excitation maximum at 401 nanometers and emission maximum of 516 nanometers, offering improved brightness to better resolve rare and low antigen density populations. It has a narrow emission profile to reduce spillover into neighboring filters and minimize excitation by other lasers, making it suitable for inclusion in multicolor panels. The dye is not susceptible to photobleaching, delivers high lot-to-lot reproducibility, and is stable at 4° C with no loss of signal, Bio-Rad said.
