rhodamine b isothiocyanate

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.

Tetramethylrhodamine B isothiocyanate (Rhodamine B, tetramethyl-, isothiocyanate) is a fluorescent dye with a strong two-photon absorption at approximately 830 nm [1].

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