Cardiogreen是一种带负电荷的聚甲炔染料，可与蛋白质形成非共价荧光复合物。这种“假荧光”特性已被用于进行蛋白测定（通过带有二极管激光诱导荧光检测的毛细管电泳进行测定）。IR 激光染料。 Cardiogreen is a negatively charged polymethine dye that forms noncovalent fluorescent complexes with proteins. This "pseudofluorogenic" property has been utilized for protein determination by capillary electrophoresis with diode laser-induced fluorescence detection.
