Acid Red 52 is a fluorescent rhodamine dye also known as Sulforhodamine B and Kiton Red, and used as a polar tracer. Ungraded products supplied by Spectrum are indicative of a grade suitable for general industrial use or research purposes and typically are not suitable for human consumption or therapeutic use.

Astrophloxine is a fluorescent dye which acts as a positively charged probe to resolve cholesterol in solution on cell membranes observed towards the spectral short-wave region. Studies suggest that Astrophloxine is beneficial in identifying the changes in the microenvironment surrounding the cell membrane. Furthermore, Astrophloxine in conjunction with microelectrophoresis can be used to research hypercholesterinemia, atherosclerosis, and D-hypovitaminosis in vitro by using the positively charge probe as a ligand to identify the compounds of interest.

An optical chemical species used in the preparation of samples for spectroscopic analysis. It is a general purpose laser that can be activated by a variety of wavelengths including radiation from the cavity or light emission. The sample cell is filled with a solution of [[(4-(tert butyl)-3,5-(dimethyl))pyrrolo[2,1,1]-benzoxazin] (DFB), which emits fluorescence upon excitation. Fluorescence lifetimes are measured using an energy efficient laser and solid phase microextraction. Optimum concentrations for DFB are about 0.05%.

7-(dimethylamino)coumarin-3-carboxylic acid is utilized as a laser dye, fluorescent label, and biomedical inhibitor in various applications.

Dansyl fluoride is a fluorogenic reagent used as a specific fluorescent probe for serine proteases and is a serine-type protease inhibitor. It is an active site directed fluorescent inhibitor of guanidinobenzoatase (GB), which binds to both the colonic isoenzymic forms of the GB. The GB on cell surfaces after binding dansyl fluoride makes the cells fluoresce blue. It has been used for the location of tumour cells in frozen sections of human lung squamous cell carcinoma and colonic carcinoma tissues. It is used as a precursor for the synthesis of other derivatives like dansyl amide. Spectral data: λex 360nm; λem 580nm (methanol).
