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。

AF488 is a bright green-fluorescent dye that is commonly used in microscopy and cell assays because of its photostability. AF488 can be used with DAPI and is well suited to multiplex assay. This high quantum yield dye has fluorescence stability within the pH range from 4 to 10.

AF488 carboxylic acid is a non-reactive AF488 form that can be used as a reference standard in experiments where AF488 conjugates are used. The carboxylic acid can be also used for the synthesis of activated esters [such as sulfo-NHS, TFP (2,3,5,6-tetrafluorophenol) and STP (4-sulfo-2,3,5,6-tetrafluorophenol)] or modified with hydrazines, hydroxylamines, or amines in aqueous solutions using water-soluble carbodiimides. Thus, this derivative can be conjugated to molecules that contain amino groups, such as proteins, antibodies, and peptides. Therefore, AF488 carboxylic acid is used during solid-phase peptide synthesis for peptide modification in situ in the presence of activating agents such as HATU.

AF488 是一种亮绿色荧光染料，因其光稳定性而常用于显微镜检查和细胞分析。 AF488 可与 DAPI 一起使用，非常适合多重检测。这种高量子产率染料在 4 到 10 的 pH 值范围内具有荧光稳定性。

AF488 羧酸是一种非反应性 AF488 形式，可在使用 AF488 偶联物的实验中用作参考标准。该羧酸还可用于合成活性酯 [例如磺基-NHS、TFP (2,3,5,6-四氟苯酚) 和 STP (4-磺基-2,3,5,6-四氟苯酚)]或使用水溶性碳二亚胺在水溶液中用肼、羟胺或胺改性。因此，这种衍生物可以与含有氨基的分子结合，例如蛋白质、抗体和肽。因此，AF488 羧酸用于固相肽合成过程中，在 HATU 等活化剂存在的情况下进行原位肽修饰。
