Nile blue A is a basic oxazine dye which is soluble in water and ethyl alcohol.Nile Blue A is used to differentiate melanins and lipofuscins. Also useful for staining fats. Used in the preparation of an amperometric glucose sensor.

Nile blue A is a satisfactory stain for PHB granules in bacteria. Poly-p3-hydroxybutyrate granules exhibits a strong orange fluorescence when stained with Nile blue A. Nile blue A appears to stain many more PHB granules than Sudan black B does and is not as easily ished from the cell by decolorization procedures[1]. Nile blue A is used as a stain for polyhydroxyalkanoic acid-accumulating microorganisms or to detect polyhydroxyalkanoic acids in microorganisms. Escherichia coli cells that do not accumulate detectable polyhydroxyalkanoic acids can be stained with Nile blue A and that this staining is sufficient for identifying these cells in fluorescence-activated cell sorting (FACS) experiments. Nile blue A staining does not affect either surface display of peptides or specific labeling of these peptides by a second fluorescence. Staining E. coli for flow cytometry using Nile blue A is an easy-to-handle and low-cost alternative to other fluorescent dyes or the intracellular expression of, for example, green fluorescent protein[2]. Nile blue A is one of the most studied benzophenoxazine dyes, as a potent photosensitizer for photodynamic therapy. The dye when administered intravenously disperses throughout the body by circulating through blood and is taken up by most cells that emphasize its interaction with various biomolecule[3].

o-Cresolphthalein Complexone is complexometric reagent derived from o-Cresolphthalein. It shows violet-red color in alkaline media and is a principle compound for the determination of hardness of water.Also used as Calcium Assay Kit as direct colorimetric assay based on the O-Cresolphtalein (OCPC) method without deproteinization of the sample. The calcium determination is based on the reaction of calcium with O-Cresolphthalein complexone in alkaline solution, which yields a violet colored complex. The intensity of the color formed is proportional to the calcium concentration in the sample. Absorbance of the Ca2+-O-Cresolphtalein complex is measured at 570nm. Wavelength range of sensitivity: 560 ~ 590nm.

o-Cresolphthalein Complexone (OCPC) method is used for colorimetric estimation of calcium in serum and determination of Magnesium, Strotium and Barium. This method is rapid, simple and ideal for routine use in clinical laboratory. Calcium in alkaline medium reacts with o-Cresolphthalein Complexone to form a purple colored complex whose absorbance is proportional to the calcium concentration. o-Cresolphthalein complexone reagent system is used for the determination of calcium in plasma or serum having increased stabillity through the use of a carbonate or bicarbonate buffer system.
