Descripción
Se ha utilizado una variedad de tintes de cianina 3 (Cy3®) para marcar moléculas biológicas para imágenes de fluorescencia y otros análisis bioquímicos basados en fluorescencia. Se utilizan ampliamente para marcar péptidos, proteínas y oligos, etc. Los tintes Cy3® tienen una fluorescencia mejorada al unirse a las proteínas. El éster Cy3® NHS reacciona fácilmente con los grupos amino.
AAT Bioquest ofrece ésteres de colorante Cy NHS en forma de sales de trietilamonio que son más solubles en DMSO y DMF que las sales de potasio correspondientes que ofrecen otros proveedores. Las sales de trietilamonio del tinte Cy tienen la misma reactividad y dan los conjugados idénticos a las sales de potasio del tinte Cy. Cy3® es la marca registrada de GE Healthcare.
