mixed isomers

Rhodamine B isothiocyanate (RITC) is a cell-permeant fluorogenic dye most often used as a conjugate to antibodies and proteins for fluorescence detection in microscopy. It displays excitation emission maxima of 570 595 nm, respectively, and can be used in conjunction with immunohistochemistry for multi-labeling studies. It has also been used as an anterograde and retrograde tracer in neurons and in nanoparticles to detect apoptosis.

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(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.

5(6)-TAMRA contains a carboxylic acid that can be used to react with primary amines via carbodiimide activation of the carboxylic acid. This bright, orange-fluorescent dye produces conjugates with absorption emission maxima of ~555 580 nm.

ROX dyes have a strong red fluorescence.Their excitation and emission wavelengths are longer than those of traditional rhodamine dyes.They are used as labels for peptides, proteins, and other biological ligands.5-ROX, 6-ROx, and their mixture of 5(6) -RoX

5(6)-TRITC [Tetramethylrhodamine-5-(and-6) -Isothiocyanate] *Mixed isomers* is used to label antibodies with strong fluorescent dyes
