SAN DIEGO--(BUSINESS WIRE)--BioLegend, Inc., a provider of antibodies and reagents for biomedical research, announced today the release of over fifty Brilliant Violet 421™ antibody conjugates for use in flow cytometry and microscopy. BioLegend developed these reagents using Brilliant Violet 421™, the first in a series of novel polymer-based fluorophores developed by Sirigen from Nobel Prize-winning chemistry. It is excited by the 405 nm violet laser, and detected with the 450/50 nm filter typically used for Pacific Blue™ and BD Horizon™ V450. Brilliant Violet 421™ antibodies provide exceptional brightness, stability, reliability, and improved signal-to-noise over Pacific Blue™ by 10-fold or more.
