rbitc [rhodamine b 5-isothiocyanate]

Rhodamine B isothiocyanate is a mixture of isomers for fluorescence applications including fluorescent marking of proteins. It is derivatite of phenolphtalein.

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-Bromo-4-chloro-3-indolyl-b-D-glucuronide sodium salt is a useful organic compound for research related to life sciences. The catalog number is T64896 and the CAS number is 129541-41-9.

Rhodamine B hydrazide serves as an effective probe for sulfite detection, transitioning from colorless and non-fluorescent to emitting Rhodamine B-like fluorescence upon interaction with sulfite (5-800 ng/mL; detection limit=1.4 ng/mL (3σ)). This process occurs as sulfite reduces dissolved oxygen, generating superoxide radicals that react with Rhodamine B hydrazide to yield Rhodamine B. The addition of Tween 80 surfactant micelles further enhances this fluorescence. The absorption and fluorescence emission maxima of Rhodamine B hydrazide are at 554 nm and 574 nm, respectively [1].

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.

Octadecyl Rhodamine B chloride, also known as RBOE, is a polarity-sensitive dye that is often used as a chromophore with other compounds to stain cell membranes and has applications in the assembly of organic molecules, in membrane structures and in the transfer of electron energy in the structural domains of proteins.

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