Fluorescent Dyes

Chemical dyes have been shown to be effective fluorescence tools in studying proteins, nucleic acids, lipid, carbohydrates, viruses, bacteria, cells, tissues, lymphokines, GPCRs, hormones and drugs.

  • Cyanine dyes can impart prominent fluorescence for detection and characterization of the study subjects. The sulfo cyanine series offer the benefit of being water-soluble with enhanced photostability and improved quantum yields. We also offer cyanine probes having reactive groups for direct bio-conjugations.
  • Fluorescein and Rhodamine dyes are widely used classic fluorescence tools. Fluorescein sodium salt, for example, has exhibited clinical indications in retinal demarcation. We also offer products having reactive groups for direct bio-conjugations.
  • Azo and Triphenylmethane dyes exhibit a plethora of applications ranging from pH indication, metal ions complexation and textile pigmentation, and they also play active roles in biological and histological staining studies.

  • Fluorescein & Rhodamine Dyes
  • Classic Azo and Triphenylmethane-type Dyes
