Staining Kit FH: Silver Impregnation after KOSSA
The staining kit LH: Silver nitrate impregnation according to KOSSA finds its application primarily in food histology to distinguish bone tissue and calcified components in tissue samples. This method provides valuable information on the quality and origin of foods.
The kit is particularly useful in the examination of meat products that may contain bone or calcified components. It allows accurate differentiation of these components from surrounding tissue, providing an effective method for quality assurance.
The staining kit contains silver nitrate, pyrogallol, potassium permanganate, a fixing mixture and orange G solution. The chemical reaction of silver nitrate with calcium compounds produces a black precipitate that is visible under a microscope. Orange G serves as a contrast dye to allow clearer differentiation.
The way the kit works is based on the specific reaction of silver nitrate with calcium compounds. Silver nitrate impregnates the calcified tissue, which then becomes visible under the microscope as black deposits. Orange G is used to stain the remaining tissue red, providing a clear contrast to the black calcium deposits.
