6-dR110 [6-Carboxy-4,7-dichlororhodamine 110] - 25 mg

Compared to fluorescein labeling reagents such as FITC and FAM, 6-dR110 [6-carboxy-4,7-dichlororhodamine 110] reagents give more photostable and pH-independent bioconjugates that have the absorption maximum around the preferred 488 nm excitation wavelength.
