Lissamine rhodamine B is a red-fluorescent dye, it is a derivative of rhodamine. Lissamine rhodamine B can be used as a fluorescent probe to develop competitive aptamer fluorescence anisotropy/polarization (FA/FP) assays[1][2].
Lissamine rhodamine B (1 mg; 1 h; room temperature; dark) can be used to detect ochratoxin A (OTA) which is a common mycotoxin[1].Lissamine rhodamine B have fluorescence properties, with the fluorescence detection conditions: excitation wavelength 555 nm, fluorescence emission spectrum detection 580 nm[1].
Lissamine rhodamine B can be used as an aradiotracer for imaging tumor mice by positron emission tomography (PET)[2].
