Basic Fuchsin 0.1 %, aqueous is a laboratory chemical used in various fields of biology and medicine. It is particularly suitable for staining biological tissue in histological and microbiological examinations. Basic fuchsin binds to nucleic acids and proteins in cells, allowing visualization of cell structures under the microscope. Interaction with tissue components produces an intense red coloration. At the same time, the concentration of 0.1% is designed for a wide range of applications and good staining results. The product enables the detection and differentiation of cell types and structures, thus supporting scientific research and diagnostics. It can be used in combination with other staining agents to realize complex staining procedures.
