Sulfo-Cyanine5.5 carboxylic acid Usage And Synthesis

Description

Sulfo-Cyanine5.5 (analog of Cy5.5?) is a water-soluble, far red emitting fluorophore. Due to four sulfo-groups, the dye possesses negative charge in neutral pH, and very high hydrophilicity._x000D_ As a cyanine dye, sulfo-Cyanine5.5 shows very low dependence of the fluorescence on pH, and very high extinction coefficient.

Uses

Sulfo-Cyanine5.5 carboxylic acidCI Pigment violet 32 is a water-soluble, far-red emitting fluorophore. Due to its four sulfo groups, this dye has a negative charge at neutral pH and is very hydrophilic. As a cyanine dye, sulfo-Cyanine5.5 shows a very low dependence of fluorescence on pH and a very high extinction coefficient.
