Three-reagent kit for staining myelin and myelinated axons, Nissl bodies and phospholipids according to Kluwer-Barrera. The kit is used for identifying the basic neuronal structure in the brain or spinal cord sections.

Two-reagent merthiolate-iodine-formalin kit for fixing and staining fecal parasites (especially protozoa, cysts, helminthic eggs and larvae). The stool sample is fixed with formalin and stained with two coloring agents; iodine and Eosin Y.

Three-reagent staining kit for connective tissue visualization and detection of collagen, cartilage, muscle, elastic fibers, mucous, pituarity cells, reticulum, bones, amyloid and erythrocytes.

Six-reagent melanin and argentaffin granule staining kit, based on the reduction of silver nitrate to elemental silver. Melanin is a brown-black pigment normally present in the hair, skin, retina, iris and certain parts of CNS. Argentaffin granules are found in carcinoid tumors.

Seven-reagent kit for staining muscle and collagen fibers with a blue counterstain. It is also used for visualizing gametes, nuclei, neurofibrils, glial cells, keratins and intercellular fibrils. The kit may be useful for detecting collagen in smooth muscle cancer or diseases like cirrhosis.

Seven-reagent kit for staining muscle and collagen fibers with green counterstain. It is also used for visualizing gametes, nuclei, neurofibrils, glial cells, keratins, intercellular fibrils and for differentiation of smooth muscle fibers and collagens.
