We would recommend this kit if the colloidal iron staining is not satisfactory.

The Copper Stain Kit is intended for the demonstration of copper deposits in tissue sections.

The Elastic Stain Kit is intended for use in histological demonstration of elastin in tissue sections. Demonstration of elastic tissue is useful in cases of emphysema (atrophy of elastic tissue), arteriosclerosis (thinning and loss of elastic fibers) and various other vascular diseases.

The Fite's Stain Kit (For Leprosy) is intended for use in the histological visualization of mycobacterium leprae (leprosy) and Nocardia.

The Fontana-Masson Stain Kit is intended for use in the histological visualization of Argentaffin cells and Melanin in paraffin or frozen sections.

The Giemsa Stain Kit (May-Grunwald) is intended for use in the visualization of cells present in hematopoietic tissues and certain microorganisms. This kit may be used on formalin-fixed, paraffin-embedded sections.

This stain kit utilizes a sulfation procedure and Toluidine Blue O to give specific metachromatic staining of Glycogen, Elastin, and Mucin (acidic and neutral) in formalin-fixed paraffin-embedded sections. Similar methods have previously been studied and referenced as Aldehyde Bisulfite Toluidine (ABT) and Permanganate Bisulfite Toluidine (PBT) staining. Glycogen may be visualized with a contrasting background as an improvement upon PAS staining.

The Modified Gomori Methenamine-Silver Nitrate Stain (GMS Stain Kit) is intended for use in the histologic visualization of fungi, basement membrane and some opportunistic organisms such as Pneumocystis carinii. Pneumocystis carinii is an opportunistic pathogen that causes severe pulmonary disease in humans, dogs, rats, mice and other vertebrate species with acquired, induced, or inherited immune deficiency syndromes. In addition, this procedure will demonstrate Actinomyces and related species, Nocardia asteroids, and certain encapsulated bacteria.

The Modified Gomori Methenamine-Silver Nitrate Stain (GMS Stain Kit) is intended for use in the histologic visualization of fungi, basement membrane and some opportunistic organisms such as Pneumocystis carinii. Periodic acid replaces traditional chromic acid as a less hazardous oxidation alternative. Background connective tissue may stain blacker in comparison with standard chromic acid oxidation.

The Gram Stain Kit is intended for the demonstration and differentiation of Gram-positive and Gram-negative bacteria.

The Gram Stain Kit (Modified Brown & Brenn) is intended for the demonstration and differentiation of Gram-positive and Gram-negative bacteria.

The H. Pylori Rapid Stain (1-Step) is a single component reagent that has been developed to identify helicobacter pylori in a procedure that requires less than 10 minutes to complete. Procedure is effective for fresh, frozen, and paraffin embedded sections. Helicobacter Pylori has been shown to be the causative organism in some gastric ulcers.

The H. Pylori Rapid Stain Kit is designed for demonstrating Helicobactor Pylori infected tissue. Kit may be used on formalin fixed, paraffin-embedded tissue. The Warthin-Starry Stain Kit (WSS-1) is a more sensitive system for H. Pylori and is suggested for cases where total H. Pylori count is low.

The Hematoxylin and Eosin Stain Kit is intended for use in histology and cytology applications. Included in this kit is a newly formulated Eosin that provides the benefits of a traditional alcoholic formula with significant improvements in usability. Advantages include lower evaporation rate, better color patterns, reduced tendency to spill over container, hands, and countertops, and improved surface tension to remain on tissue section. Our Hematoxylin produces crisp, intense blue nuclei providing optimal contrast to the Eosin stained cytoplasm.

The Herovici stain kit is intended to differentiate between young and mature collagen. Young collagen and reticulin stain blue and Mature collagen stains red. Weigert's Iron Hematoxylin is provided to stain nuclei blue to black.

The Iron Stain Kit is intended for use in the detection of ferric iron in tissues, blood smears, or bone marrow smears. Ferric iron is normally found in small amounts in bone marrow and the spleen. Abnormally large deposits may be seen in hemochromatosis and hemosiderosis. This product is based on the Prussian Blue reaction in which ionic iron reacts with acid ferrocyanide producing a blue color.

The Jones Stain Kit is intended for use in histological demonstration of the basement membrane and reticular fibers. This procedure is ideal for staining renal glomerular basement membranes. The main function of the basement membrane and reticular fibers is to provide anchorage and support. They are normally found throughout the body, particularly in the kidney, spleen, and lung.

The use of Crystal Violet for metachromatically staining amyloid was published in 1947 by Ethel Lieb. This stain utilizes a water-reliant metachromatic staining reaction giving reddish amyloid with a blue background. A water-based mounting medium is required to retain permanence of red amyloid coloring.

The Luxol Fast Blue Stain Kit is designed for staining myelin/myelinated axons and Nissil substance on formalin fixed, paraffin-embedded tissue. This product is used for identifying the basic neuronal structure in brain or spinal cord sections.

The Martius Scarlet Blue (MSB) stain kit is intended for use in the histological demonstration of fibrin, muscle, collagen, and erythrocytes. MSB is a reliable method of differentiating fresh and old fibrin clusters.

The Movat Pentachrome Stain Kit (Modified Movat) is intended for use in histological demonstration of collagen, elastin, muscle, mucin and fibrin in tissue sections. This procedure is particularly useful when studying the heart, blood vessels and various vascular diseases.

Mucicarmine Stain Kit (Modified Southgate's) is intended for use in the histological visualization of acid mucopolysacharides in tissue sections. This product is useful in distinguishing mucin negative undifferentiated squamous cell lesions from mucin positive adenocarcinomas. In addition, this product will stain the mucopolysaccharide capsule of Cryptococcus neoformans.
