5-Carboxyrhodamine 110 NHS Ester is the nonsulfonated analog of the BP Fluor 488 dye. The amine-reactive 5(6)-Carboxyrhodamine 110 NHS Ester can be used to create bright and photostable green-fluorescent bioconjugates with excitation/emission maxima ~502/527 nm. For many applications, the dye is preferred over 5-(6)-carboxyfluorescein NHS ester or FITC because of its exceptional photostability and fluorescence insensitivity to pH (4-9). Although the mixed isomers of Carboxyrhodamine 110 NHS Ester preferred, routinely used fluorescent dye for labeling proteins, peptides and nucleotides, purification of peptide and nucleotides labeled with 5(6) isomers might be troublesome due to significant signal broadening in HPLC purification. Peptides and nucleotides labeled with a single isomer usually give better resolution in HPLC purification that is often required in the conjugation processes.

Cyanine3B azide for click chemistry conjugation with terminal alkynes via a copper-catalyzed click reaction or strained cyclooctynes via a copper-free click reaction. Cyanine3B is a yellow-emitting cyanine dye that is an improved version of the Cyanine3 fluorophore with significantly higher fluorescence quantum yield and photostability. Due to the fixed conformation, Cyanine3B has the highest emission quantum yield compared to other dyes of this wavelength. This is a non-sulfonated dye that requires an organic co-solvent (DMF, DMSO, or other) for efficient labeling in water.

CSMPP is a ratiometric lysosomal pH fluorescent probe with aggregation-induced emission (AIE) properties, which is used for real-time quantitative detection of lysosomal pH changes in living cells and in vivo. CSMPP has a cyanodistyrene backbone, and contains N-methylpiperazine and pyridine groups (pH-responsive); protonation of the pyridine group significantly enhances intramolecular charge transfer (ICT), leading to green fluorescence emission (Ex/Em = 405/503 nm) under neutral/basic conditions and red fluorescence emission (Ex/Em = 405/615 nm) under acidic conditions. CSMPP exhibits high selectivity, reversibility, good biocompatibility and excellent photostability .

BP Fluor 532 maleimide is a photostable, bright yellow-fluorescent dye with pH insensitive emission from pH 4 to pH 10. The excitation of BP Fluor 532 is ideally suited for the frequency-doubled Nd:YAG laser line. BP Fluor 532 dye can be conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates, and is often used for the generation of stable signals in imaging and flow cytometry. Maleimide is the most popular sulfhydryl-reactive group for conjugating the dye to a thiol group on a protein, oligonucleotide thiophosphate, or low molecular weight ligand. The maleimide group specifically and efficiently reacts with reduced thiols (sulfhydryl groups, –SH) at pH 6.5 to 7.5 to form a stable thioether bond. The resulting conjugates exhibit brighter fluorescence and greater photostability than the conjugates of many other spectrally similar fluorophores.
