The product is supplied as a powder.
Rhodamine B Isothiocyanate can be used for various applications. The only suitability test performed during quality control testing is for labelling efficiency with Bovine Serum Albumin. There is no suitability testing or protocol available for conjugating chitosan polymers. A search of the literature will be required to locate a protocol.

General description
Rhodamine B isothiocyanate (RhBITC) is an organic fluorescence dye and is widely used as a fluorescent tag in a variety of biological applications. RhBITC is adsorbed onto Ag on silica or polystyrene beads. It exhibits not only a strong surface-enhanced Raman scattering (SERS) signal but also a measurable amount of fluorescence. The RhBITC-modified Ag-deposited silica or polystyrene beads disperse well in ethanol. They are also readily coated in water with polyelectrolytes for their further derivatization with biological molecules of interest that can bind to target molecules.
