Mayers Hematoxylin H4g ...................................................
For use in both cytology and histology.
General purpose nuclear stain, progressive type. Used with hematoxylin and eosin staining.
Scott’s Bluing Reagent A2g ..................................................
A gentle formulation of “bluing” reagent for those specimens that may be affected by more
harsh “bluing” agents. Our premixed and ready to use Scott’s Bluing Reagent provides rapid
bluing and crisp nuclear detail obtained with routine Hematoxylin and Eosin stains. For use in
both Cytology and Histology.
Silver Stains
New! Fontana Masson Stain Kit ..............................................
Intended for the use in the histological visualization of Argentaffin cells and
Melanin in paraffin or frozen sections. Technical Data Sheet #893
Kit Contains: 10% Silver Nitrate, 0.1% Gold Chloride, 28-30% Ammonium
Hydroxide, 1% Nuclear Fast Red, and 5% Sodium Thiosulfate.
New! Grocott Methenamine Silver Stain (GMS) for Fungus & PCP ...................
Chromic acid oxidation forms aldehydes from fungal cell wall polysaccharide
components, which are subsequently demonstrated by reduction of an alkaline
hexamine-silver complex. The reaction may be compared to that of the Periodic
Acid Schiff reaction. 3.8% chromium trioxide aqueous soln. (500ml)
Technical Data Sheet #864
Kit Contains: Chromic Acid Soln., Sodium Metabisulfite, 5% Silver Nitrate,
Methenamine Soln., 5% Borax, 0.2% Gold Chloride, 2% Sodium Thiosulphate,
Light Green stock soln.
New! Jones PAS-M Stain Kit .................................................
Periodic Acid Schiff Methenamine Silver Stain for Basement Membranes
A new and improved Jones PAS-M technique that utilizes an enhancer to
accelerate the methenamine silver reaction with the glomerular basement
membranes, while reducing the time to achieve results better than the original
Jones PAS-M and a more stabilized silver solution. Used in kidney biopsies,
Jones PAS-M may also be used for plastic sections for glomerular and tubular
basement membranes. Technical Data Sheet #868
Kit Contains: 0.5% Periodic Acid, 0.5% Thiosemicarbazide, 5% Silver Nitrate Stock, 3% Methenamine,
3% Borax, 0.2% Gold Chloride, 2% Sodium Thiosulphate, Nuclear Fast Red
New! Reticulin Stain Kit .....................................................
Identifies reticulin fibers in tissue sections liver, kidney and spleen. Reticulin is a
type III collagen found in the basement membrane of many organs and provides
structural integrity. Reticulin Stain Kit is a metal impregnation technique, where
ammoniacal silver initially binds to the tissue component of interest, the reducing
agent (formalin) produces a dark insoluble precipitate, then treated by toning
and fixing in sodium thiosulfate. Technical Data Sheet #876
Kit Contains: 1% Potassium Permanganate, Oxalic Acid, 2.5% Ferric Ammonium
Sulfate, 10% Silver Nitrate, 28-30% ACS Ammonium Hydroxide, 3% Sodium Hydroxide, 10% Formalin
Aqueous Soln., 0.2% Gold Chloride, 5% Sodium Thiosulfate, 1% Nuclear Fast Red Stain Soln.
New! Steiner & Steiner Stain Kit .............................................
Useful to aide in the diagnosis of diseases such as Syphilis, some gastric ulcers,
H. pylori, Lyme disease, Legionnaires’ disease, Cat Scratch fever and others
dependent on staining of the causative organisms. Technical Data Sheet #895
Kit Contains: 1% Uranyl Nitrate Solution, 2% Hydroquinone, 10% Gum
mastic, 0.5% Gum mastic, and 3% Silver Nitrate.
