Free Dyes
Near-IR CF® dye free acids are control dyes for studies that involve Near-IR CF® dye succinimidyl ester conjugated to antibody, protein or peptides. We also offer a selection of classic dye free acids.

Carboxyrhodamine 110 hydrochloride, 5 and 6 isomers
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.
