The staining kit LH: Elastica according to HART is used in food histology to visualize elastic fibers in tissue samples. The differentiated visualization enables a precise analysis of the tissue composition and thus supports qualitative investigations.

The kit is particularly suitable for the identification of elastic fibers, which play a decisive role in the assessment of the texture and quality of foods. With its help, elastic fibers can be differentiated and characterized from other tissue components.

The staining kit consists of resorcinol-fuchsin and orange G solution. Resorcinol-fuchsin, a red dye, specifically interacts with elastic fibers and imparts intense staining. Orange G, a yellow dye, is used for contrast staining to enhance differentiation.

The kit works based on the specific interaction of the dyes with tissue components. Resorcinol-fuchsin binds to elastic fibers, while orange G binds predominantly to other tissue components. The different staining of the components enables a differentiated visualization, which allows a precise assessment of the tissue structure and composition.
