"Gram Stain Kits – Tissue & Film
Bacteria can be classified into one of two families based upon structural and compositional differences in their cell walls. Gram-positive bacteria have thick cell walls with high peptidoglycan content, whereas Gram-negative bacteria have thin cell walls with low peptidoglycan content. Both Gram-positive and Gram-negative bacteria stain with the dye- lake formed by Crystal Violet Solution and Gram’s Iodine Solution. However, during rinsing with Decolorizing Solution, this dye-lake is completely removed from the thin-walled Gram- negative bacteria, allowing them to be subsequently stained with Safranin O Stain Solution. The short duration of the decolorization step enables Gram-positive bacteria to retain the crystal violet dye-lake. Care should be taken when rinsing slides with Decolorizing Solution, as extended rinses can cause the crystal violet dye-lake to be removed from Gram-positive bacteria in addition to Gram-negative bacteria. Within the Tissue Kit only, tissue elements are then counterstained yellow by Tartrazine Stain Solution."

Modified Steiner-Steiner Silver Stain Kit aids in identifying spirochetes and non-filamentous bacteria in tissue sections for the diagnosis of general pathology specimens. Microorganisms that stain positively with this technique have a cell wall that will adsorb silver from a silver solution (argyrophilic). The silver is first adsorbed in a non-visible form and is subsequently reduced by the Working Reducing Solution (hydroquinone) to a visible metallic silver.

Gomori’s Trichrome Stain Kit Green Collagen and its components are used as a special stain kit to distinguish between collagen and muscle fibers. The cytoplasmic stain and the collagen stain are combined into one solution along with phosphotungstic-phosphomolybdic and glacial acetic acids. Muscle cells and cytoplasm favor the red dyes, and this is facilitated by the phosphotungstic acid. Collagen fibers take up the tungstate ion, allowing for the green dye to selectively bind.
