Acridine Orange base is a cell-permeable fluorescent dye that stains organisms (bacteria, parasites, viruses, etc.) bright orange and, when used under appropriate conditions (pH=3.5, Ex=460 nm), distinguishes human cells in green for detection by fluorescence microscopy. Acridine Orange base fluoresces green when bound to dsDNA (Ex=488, Em=520-524) and red when bound to ssDNA (Ex=457, Em=630-644) or ssRNA (Ex=457, Em=630-644), also can be used in cell cycle assays .

Ruthenium red (Ammoniated ruthenium oxychloride) is a polycationic dye widely used for electron microscopy (EM) of cells, tissues and vegetative bacteria. Ruthenium red strongly reacts with phospholipids and fatty acids and binds to acidic mucopolysaccharides. Ruthenium red is a L-type calcium current (ICa) blocker. When using Ruthenium Red to stain plant tissue sections affected by pathogens, the breakdown of mucilaginous substances by the pathogens prevents them from taking up the stain, whereas the cell walls of healthy tissue stain red .

CAS No.: 61926-22-5
Synonyms: EthD-1
Ethidium homodimer (EthD-1) is a high-affinity fluorescent nucleic acid dye commonly used to stain mammals, bacteria, yeast, and fungi. Ethidium homodimer binds to DNA or RNA, enhancing fluorescence more than 30 times. The Ethidium homodimer has a strong positive charge, so it cannot cross cell membranes and stain living cells; But the Ethidium homodimer can cross the disordered region of the dead cell membrane to reach the nucleus and embed the DNA double strand to produce red fluorescence. Therefore, Ethidium homodimer is a relatively sensitive nucleic acid stain that can accurately detect nucleic acids in solution or in decomposing cells. Ethidium homodimer binds DNA, Ex/Em=528/617 nm .

Synonyms: WGA (Fluorescein)
Wheat Germ Agglutinin (WGA) Fluorescein is a classic fluorescent label that specifically binds to sugar residues such as N-acetylglucosamine, N-acetylneuraminic acid and sialic acid. Wheat Germ Agglutinin Fluorescein performs regionally differential fluorescent staining of the ocular surface epithelial glycocalyx to assess its integrity, and causes no damage to the eye at safe concentrations. Wheat Germ Agglutinin Fluorescein is also used for staining structures including red blood cells, cultured cells, bacteria and pine wood nematodes, and facilitates the isolation of wheat-associated plant-growth-promoting rhizobacterial strains. Wheat Germ Agglutinin Fluorescein can be applied to the detection of ocular glycocalyx integrity and the research of related diseases such as pine wilt disease .

Carbol fuchsin is a histological stain used in microbiology to distinguish acid-fast bacteria from non-acid-fast bacteria. It is a mixture of basic fuchsin, phenol, and water and is commonly used in the Ziehl-Neelsen staining technique for the detection of tuberculosis and other mycobacterial infections. Carbol fuchsin stains the cell walls of acid-fast bacteria bright red, while other cells are unstained or slightly stained. This makes it easier to see and identify these microbes under a microscope. Carbol fuchsin is also used in veterinary medicine and phytopathology for similar purposes.
