Rhodamine B isothiocyanate (RBITC) is a reactive fluorescent dye widely used for covalent labeling of biomolecules in imaging and analytical applications. The isothiocyanate functional group readily reacts with primary amines on proteins, peptides, and other biomolecules to form stable thiourea linkages, enabling durable fluorescent tagging.
RBITC emits bright orange-red fluorescence upon green light excitation, providing strong signal intensity and excellent photostability for visualization in complex biological systems. Owing to its high sensitivity, chemical stability, and compatibility with diverse assay conditions, RBITC is extensively utilized in cell biology, immunology, neurobiology, and fluorescence microscopy studies for tracking molecular localization and dynamics.
