Fluorescent Probes and 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 probes 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.

	Product Name: 6-FITC (3',6'-Dihydroxy-6-isothiocyanatospiro[isobenzofuran-1(3H),9'-[9H]xanthen]-3-one) Order number: 204576 CAS: 3326-31-6 Purity: >=95% Appearance: solid MF: C21H11NO5S MW: 389.381 MP: n.a. oC Description: This fluorescein dye has been used conjugation with antibodies including the flow cytometry. With the isocyanate reactive group, the dye is capable of conjugating with peptides and proteins having cysteine residue (containing sulfhydryl SH) and lysine residue (containing terminal amine NH2). Addition of SH to isothiocyanate is faster to form dithiocarbamate which is converted to more stable thiour Login to check availability and price information.
