The FCA staining kit according to Etzold (SAFELINE) is specially designed for botanical applications. The fuchsin-chrysoidin-astrac blue solution included in the kit provides differentiated visualization of various plant tissue types by highlighting cell walls, nuclei and cytoplasm in different colors. SAFELINE INCLUDAL A is used to pretreat samples, while Rinsing Solutions 1 and 2 remove excess dye to provide clear, precise staining. Finally, SAFELINE Fixing Solution FCA fixes the stain for long-lasting results. The chemical properties of these solutions allow for optimal staining and improved microscopic differentiation of various tissue types. With the use of this kit, researchers can analyze botanical samples and produce detailed, high-contrast images that show both the structure and composition of plant cells.
