The immobilized form of Fast Red TR salt hemi(zinc chloride) is a dye that is used in histology to detect and measure lipids. It is especially useful for the detection of lipoproteins. The fluorescence of this compound is quenched by proteins but not by phosphatidylcholine, which makes it an excellent marker for detecting lipoproteins. Fast Red TR salt hemi(zinc chloride) can be used to stain sections of tissue or cells with a maldi-tof mass spectrometer. The immobilized form of this dye becomes fluorescent when contacted with an oxidizing agent such as hydrogen peroxide, which is present during the staining process. This allows for the detection and measurement of lipid content within cells on a histological section, giving information about the cell type and degree of differentiation. Staining with Fast Red TR salt hemi(zinc chloride) only takes a few minutes, and after staining, sections can
