The BD Horizon™ Brilliant Stain Buffer is a buffer for the immunofluorescent staining of cells. Brilliant Stain Buffer is a solution that is added to mixtures of certain fluorescent reagents before staining cells. It was designed to complement multicolor flow cytometry experiments that utilize staining reagents conjugated with BD Horizon Brilliant fluorescent polymer dyes. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime BD Horizon Brilliant dyes are used. The BD Horizon Brilliant Stain Buffer is compatible with the use of other fluorescent staining reagents conjugated with traditional fluorochromes, such as fluorescein, phycoerythrin or Alexa Fluor® dyes.
