Cyanine3.5 is a fluorescent dye with absorption and emission intermediate between Cyanine3 and Cyanine5. Sulfonated version contains four sulfo groups which ensure high solubility and hydrophilicity of the fluorophore and labeled conjugates.
The NHS ester reactive group allows to label primary and secondary amine groups.
Cyanine3.5 是一种荧光染料，具有介于 Cyanine3 和 Cyanine5 之间的吸收和发射中间体。 磺化版本包含四个磺基，可确保荧光团和标记偶联物的高溶解度和亲水性。
NHS 酯反应基团允许标记伯胺和仲胺基团。
