Designing high-performance flow cytometry and fluorescent western blot panels often requires antibody and fluorophore combinations that are not commercially available. Bio-Rad's expanded range of TrailBlazer™ StarBright™ Dye Label Kits gives researchers greater freedom to create custom conjugates while maintaining the brightness, stability and performance expected from StarBright dyes.
The expanded portfolio now includes 32 dye label kits covering UltraViolet, Violet, Blue, Yellow and Red fluorophores. When used alongside the TrailBlazer Tag Kit, the system employs SpyTag and SpyCatcher technology to produce highly stable antibody conjugates suitable for demanding research applications in immunology, cell biology and related fields.
StarBright dyes are proprietary fluorescent nanoparticles designed to deliver exceptional brightness with narrow excitation and emission profiles, helping researchers resolve complex cell populations while reducing spectral spillover. Compatible with most flow cytometers and standard laboratory workflows, the dyes require no specialist buffers and exhibit excellent resistance to photobleaching, ensuring consistent performance throughout experiments.
The expanded range also benefits fluorescent western blotting. StarBright Blue 520 and StarBright Blue 700 have been optimised for use with Bio-Rad's ChemiDoc imaging systems, providing bright fluorescent detection with short exposure times and excellent sensitivity.
Broad antibody compatibility, long-term conjugate stability and minimal lot-to-lot variation help researchers generate reliable, reproducible data while simplifying panel design. By expanding access to custom antibody-fluorophore combinations, the TrailBlazer StarBright Dye Label Kits provide a flexible solution for laboratories looking to optimise assay performance and streamline experimental workflows.
