rhodamine 110

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

5(6)-carbonylated rhodamine 110 NHS ester is a reactive ester fluorescent reagent based on 5(6)-carbonylated rhodamine 110. The NHS ester acts as a highly reactive active ester that can covalently couple with primary amine groups in proteins, polypeptides, amino sugars, and nucleic acids to form stable amide bonds (Ex/Em = 502/527 nm).

5(6)-Carbonylated rhodamine 110 X NHS ester is an active ester-based fluorescent reagent derived from 5(6)-carbonylated rhodamine 110 X. The NHS ester is highly reactive, allowing it to form stable amide bonds through covalent coupling with primary amine groups in proteins, peptides, aminoglycosides, nucleic acids, and other molecules (Ex/Em = 496/522 nm).

5(6)-Carbonylated rhodamine 110 maleimide is a fluorescent reagent based on 5(6)-carbonylated rhodamine 110, classified under maleimides. Maleimide can react with thiol groups (-SH) through a Michael addition reaction to form a stable thioester structure for labeling purposes (Ex/Em = 502/527 nm).

5(6)-carbonylated rhodamine 110 amine is a primary amine-based fluorescent reagent derived from 5(6)-carbonylated rhodamine 110. The primary amine can form covalent bonds with various functional groups, including carboxylic acids, active esters (such as NHS esters), and isothiocyanates, enabling labeling (Ex/Em = 502/527 nm).

5(6)-Carboxyrhodamine 110 NHS ester is the non-sulfonated analog of BP Fluor 488 dye. It is used to create bright and photostable green fluorescent bioconjugates with excitation/emission maxima around 502/527 nm. Conjugates of this dye are typically employed in fluorescence correlation spectroscopy (FCS).

5(6)-Carboxyrhodamine 110 is an amine-reactive fluorescent probe used for labeling DNA, cells, and proteins (Ex/Em = 498/530 nm).

5(6)-CR110 [5-(and 6)-Carboxyrhodamine 110] *Mixed isomers* 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.

5-CR110 [5-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.

5(6)-CR110, SE [5-(and 6)-Carboxyrhodamine 110, succinimidyl ester] *Mixed isomers* 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.

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 489 nm excitation wavelength. They are photostable alternative reag

6-CR110, SE [6-Carboxyrhodamine 110, succinimidyl ester]*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.

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.
