Water soluble fluors useful in enhancing images obtained in autoradiography have the general formula:
F is a moiety which acts as a fluor, e.g., a dehydro derivative of a compound which is a fluor; preferred examples include 4-(2,5-diphenyloxazolyl), 1-naphthyl-methyl, 2-naphthyl, and 4-[5-(2-phenyloxazolyl)]phenyl. S is a surfactant moiety which makes the molecule hydrophilic, e.g., dehydro derivatives of surfactants; preferred examples include polyethylene glycol derivatives, sulfonic acids or salts thereof, aryl sulfonates, amines and quaternary ammonium compounds. B is a binding moiety which chemically binds the fluor moiety F with the surfactant S, and may be a chemical bond, or a disubstituted moiety such as an alkylene, e.g., methylene group. The variables x, y and z are integers which can generally vary from 1 to 10. A number of such compounds are disclosed, as well as methods of using such compounds, as well as compositions and products for fluorographic analysis in connection with chromatography, electrophoresis etc.
可用于增强自动射线照相术图像的水溶性荧光剂具有以下通式:
F 是起荧光剂作用的分子,如荧光剂化合物的脱氢衍生物;首选的例子包括 4-(2,5-二苯基恶唑基)、1-萘甲基、2-萘基和 4-[5-(2-苯基恶唑基)]苯基。S 是使分子亲水的表面活性剂分子,如表面活性剂的脱氢衍生物;首选的例子包括聚乙二醇衍生物、磺酸或其盐、芳基磺酸盐、胺和季铵化合物。B 是将氟分子 F 与表面活性剂 S 化学结合的结合基,可以是化学键,也可以是二取代基,如亚 烷基,如亚甲基。变量 x、y 和 z 是整数,一般可在 1 到 10 之间变化。本发明公开了许多此类化合物、使用此类化合物的方法以及与色谱法、电泳法等有关的荧光分析组合物和产品。
