Carboxyrhodamine 110 hydrochloride, 5 and 6 isomers

From: $188 Sizes: 10 mgCatalog #: 90000

For some applications, 5-(and-6)-carboxyrhodamine (5(6)-CR 110) is a superior alternative to the widely used green fluorescent dye 5-(and-6)-carboxyfluorescein. The dye is insensitive to pH between 4 and 9 and is much more photostable than fluorescein.
