Chemical properties of Weigert's resorcin-fuchsin, orcinol-new fuchsin, Sheridan's crystal violet and their resorcinol-free analogues were investigated using reverse-phase and gel filtration chromatography, electrophoresis, and visible light spectroscopy. Their staining properties were also studied. It was concluded that 1) the staining
