Sulfo-Cyanine3.5 carboxylic acid

Sulfo-Cyanine3.5 is a cyanine fluorophore with fluorescence in the orange spectrum range. Its absorption and emission spectra are between those of Cyanine3 and Cyanine5.

This dye is a sulfonated form of Cyanine3.5 (contains four sulfo groups), so it has good solubility and can be used in reactions without adding organic solvents.

This reagent is a derivative with a free carboxyl group. Because of its inactivity in physiological conditions, sulfo-Cyanine3.5 carboxylic acid derivative can be used as a negative control in experiments with active dye derivatives. The carboxylic acid can be activated with carbodiimides (e. g. EDAC) and react with hydrazines, hydroxylamines, and amines.

Sulfo-Cy3.5 是一种花青荧光团，在橙色光谱范围内具有荧光。 其吸收和发射光谱介于花青 3 和花青 5 之间。

该染料是Cyanine3.5的磺化形式（含有四个磺基），因此具有良好的溶解性，可以在不添加有机溶剂的情况下用于反应。

该试剂是具有游离羧基的衍生物。 由于其在生理条件下无活性，磺基-Cyanine3.5 羧酸衍生物可用作活性染料衍生物实验中的阴性对照。 羧酸可以用碳二亚胺（例如 EDAC）活化并与肼、羟胺和胺反应。
