Description
Suitable for fluorescent labellingRhodamine B is used as a laser dye, metal chelating agent and an additive to drugs and cosmetics. It also serves as a staining fluorescent dye, which is used as a colorant in inks, paper and plastics. Further, it is used to make pink fluorescent pigments. It is also employed as a biomarker in oral rabies vaccines for wildlife such as raccoons. In addition to this, it is a useful fluorochrome for histology, fluorescence resonance energy transfer (FRET) and mitochondrial probe.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
