一般說明

荧光素5（6）-异硫氰酸酯，也称为FITC，是一种弱酸性的羟基黄酮类化合物，其整体尺寸较小，在苯环上具有羧酸和异硫氰酸酯基团。这种染料具有中等大小、非平面的芳香环系。 异硫氰酸酯基团与生物分子的亲核官能团（如氨基，羟基，巯基）反应，作为荧光标记物附加在生物分子上。 该染料在相同溶剂中的最大发射波长为519纳米。

應用

用于蛋白质的荧光标记（例如免疫荧光）;凝胶色谱中的 H 蛋白质标记
荧光素5(6)-异硫氰酸(FITC)标记的分子用于非显微免疫测定和生理示踪实验。FITC在流式细胞术实验中广泛用于蛋白质、细胞核和亚核颗粒的染色。 使用FITC标记的白细胞（WBC）可用于研究其对趋化因子的反应性并进行最终测定。
