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.

Structure	Details
	Product Name: Cy3 Order number: 204588 CAS: 146368-13-0 Purity: >=95% Appearance: solid MF: C31H38N2O8S2 MW: 630.771 MP: n.a. oC Description: This carboxyl, water soluble sulfo cyanine dye, Cy3, is a reference fluorophore for detection channel. Once the carboxyl group (COOH) is made reactive, it can be used to bioconjugate with peptides and proteins (via amide formation) to produce strong fluorescence. As well, cy3 can be also a good probe to detect nucleic acids. Login to check availability and price information.
	Product Name: Cy3-SE Order number: 204589 CAS: 146368-16-3 Purity: >=95% Appearance: solid MF: C35H41N3O10S2 MW: 727.844 MP: n.a. oC Description: This water soluble, sulfo reactive cyanine dye, Cy3-SE, uses its reactive hydroxysuccimide to conjugate with NH2 group in biomolecules such as peptides, proteins, nucleic acid derivatives, and drugs to achieve possibly enhanced fluorescence intensity and imaging resolution due to effective staining.

	Product Name: Cy5 Order number: 204590 CAS: 146368-11-8 Purity: >=95% Appearance: solid MF: C33H40N2O8S2 MW: 656.809 MP: n.a. oC Description: This water soluble, sulfo carboxyl cyanine dye has two more methines than Cy3, therefore is bathochromic. It is a reference fluorophore for detection channel. If the carboxyl group (COOH) is made reactive, it can bioconjugate with peptides and proteins (via amide formation) to produce strong fluorescence. As well, Cy5 can be also a good probe to detect nucleic acids. Login to check availability and price information.
	Product Name: Cy5-SE Order number: 204591 CAS: 146368-14-1 Purity: >=95% Appearance: solid MF: C37H43N3O10S2 MW: 753.882 MP: n.a. oC Description: This reactive, water soluble sulfo cyanine dye has two more methines than Cy3-SE and is bathochromic. It uses its reactive hydroxysuccimide to conjugate with NH2 group in biomolecules such as peptides, proteins, nucleic acid derivatives, and drugs to achieve possibly enhanced fluorescence intensity and imaging resolution due to effective staining.

	Product Name: Cy7 Order number: 204592 CAS: 943298-08-6 Purity: >=95% Appearance: solid MF: C35H42N2O8S2 MW: 682.847 MP: n.a. oC Description: This carboxyl water soluble sulfo cyanine dye has two more methines than Cy5, therefore is bathochromic. It is a reference fluorophore for detection channel. Once the carboxyl group (COOH) is made reactive, it can be used to bioconjugate with peptides and proteins (via amide formation) to produce strong fluorescence. As well, Cy7 can be also a good probe to detect nucleic acids. Login to check availability and price information.
	Product Name: Cy7-SE Order number: 204593 CAS: 477908-53-5 Purity: >=95% Appearance: solid MF: C39H45N3O10S2 MW: 779.92 MP: n.a. oC Description: This reactive, water soluble sulfo cyanine dye has two more methines than Cy5-SE and is bathochromic. It uses its reactive hydroxysuccimide to conjugate with NH2 group in biomolecules such as peptides, proteins, nucleic acid derivatives, and drugs to achieve enhanced fluorescence intensity and imaging resolution due to effective staining.
