rhodamine-110

Rhodamine 110 (RH110) is a xanthene dye similar to fluorescein and eosin.

Z-DEVD-R110 ((Z-Asp-Glu-Val-Asp) 2 -Rhodamine 110), a rhodamine derivative featuring two four–amino acid (DEVD) peptides attached to the fluorophore [1], serves as a fluorogenic substrate for caspase-3 7. This compound is utilized for detecting apoptosis, leveraging its design to bind and indicate caspase activation.

6-CR110 [6-Carboxyrhodamine 110] *Single isomer* is a Fluorescein for peptide and oligonucleotide labeling. Compared to fluorescein labeling reagents such as FITC and FAM, CR110 reagents give more photostable and pH-independent bioconjugates that have the absorption maximum around the preferred 488 nm excitation wavelength. They are photostable alternative reagents superior to FITC and FAM.
