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.
Near-IR CF® Dye Free Acids
Non-reactive, free acid forms of the near-infrared (NIR) CF® dyes that can be used as controls for the corresponding dye-conjugates. Available with the following CF® dyes: CF®680, CF®750, CF®770, and CF®790.

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.
