Blue Feulgen DNA Ploidy Analysis Staining Kit

Larger picture

The Blue Feulgen DNA Ploidy Analysis Staining Kit is a histochemical reagent kit for quantifying the nuclear DNA content in cells. The kit can be used on a variety of specimen types from cytocentrifuge preparations to formalin fixed paraffin embedded tissue sections. A unique formulation eliminates dye precipitation and results in a cleaner stain than conventional Feulgen reagent-based kits. This stain kit is optimized for DNA Ploidy specimens that will be stained then scanned and viewed on image analysis systems.

The basis of the Feulgen staining procedure is the use of an acid hydrolysis step to remove purines from the deoxyribose backbone of the DNA molecule. The newly exposed deoxyribose sugars have an aldehyde group, and this can then be identified by staining with a Schiff reagent (in this case, an aqueous solution of cresyl-violet and sulfurous acid used to test for the presence of aldehydes).

The amount of stain color developed is directly proportional to the amount of DNA present in the stained cells.

Storage: 2-8 deg. C.

Kit Contents: 2 x 500ml Bottles of Ready-To-Use Liquid Stain
10 vials of Decolorizer
10 vials of Rinse Buffer

Eosin Y - Phloxine

Larger picture

Eosin-Phloxine Solution is intended for use in the histological demonstration of cytoplasm. The addition of Phloxine to Eosin results in more vibrant staining than with Eosin alone. When used correctly, Eosin-Phloxine various shades of pink can be obtained to aid in visualization of tissue components.

Cytoplasm:           Pink to Red
Erythrocytes:        Pink to Red
Alcoholic Hyalin:    Pink

GMS Stain Kit

Larger picture

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.

Iron Stain Kit

Larger picture

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.

Tissue Sections:

Iron:                 Bright Blue
Nuclei:             Red
Background:    Pink
