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.

Gram Control Slides contain a section of gram-positive and gram-negative staining rat lung and a section of human lung nonreactive to organisms. The positive control slides are intended to be used to verify histological techniques and reagent reactivity and are not intended to be used for any quantitative purpose.
Tissues are from human tissue, formaldehyde-fixed, paraffin-embedded, heat dried and cut at 5 microns unless otherwise specified. Standard tissue placement is mid-range of the slide.

The Gram Stain Kit is intended for the demonstration and differentiation of Gram-positive and Gram-negative bacteria. Gram staining is a common technique used to differentiate between two large groups of bacteria based upon cellular wall composition, coloring Gram-positive and Gram-negative groups red or violet. Gram-positive bacteria will stain violet by retaining crystal violet in a thick layer of peptidoglycan in their cell walls. Gram-negative bacteria will stain red because crystal violet in not retained in the thinner peptidoglycan wall during the decoloring process.
Gram Positive Bacteria: Blue
Gram Negative Bacteria: Red
Other Tissue: Yellow
Nuclei: Red

Stains for gram-positive and gram-negative bacteria in just 10 minutes.
The Gram Stain Kit (Modified Brown & Brenn) is intended for the demonstration and differentiation of Gram-positive and Gram-negative bacteria. In the Brown & Brenn protocol, Safranin O and Hucker€™s Gentian Violet both serve as primary stains that produce blue stained gram-positive bacteria and red gram-negative bacteria and nuclei. Picric Acid/Acetone is used as a yellow counterstain.
Gram Positive Bacteria: Blue
Gram Negative Bacteria: Red
Other Tissue: Slightly Yellow - Pink
Nuclei: Red

Helicobacter Pylori slides have sections of positive staining gastrointestinal tissue and negative staining lung. The positive control slides are intended to be used to verify histological techniques and reagent reactivity and are not intended to be used for any quantitative purpose.
Tissues are from human tissue, formaldehyde-fixed, paraffin-embedded, heat dried and cut at 5 microns unless otherwise specified. Standard tissue placement is mid-range of the slide.

Description
Our Hematoxylin and Eosin Staining Kit makes it easy to produce reproducible, high quality H&E histology. The kit contains everything needed for Hematoxylin and Eosin staining and is intended for use in histology and cytology applications. Included in this kit is an optimized formulation of Eosin Y that provides the benefits of a traditional alcoholic formula with significant improvements in usability. Advantages of our kit include lower evaporation rates, better color patterns, a reduced tendency to spill over containers, hands, and countertops, and improved surface tension to remain on tissue section. Mayer's Hematoxylin (Lillie's Modification) produces crisp, intense blue nuclei that provides optimal contrast to the Eosin stained cytoplasm.
Comes with 500 ml bottles (each) of hematoxylin, eosin, and bluing reagent solutions, sufficient for hundreds of slides.

Hollande's is a fixative useful for routine procedures, and is widely used as a fixative for biopsy specimens of the gastrointestinal tract. Hollande's contains formaldehyde for cytoplasmic fixation. It is stable and will decalcify small bone specimens. Tissue that is fixed with Hollande's can be stained successfully with most stains, and the cupric acetate in the solution stabilizes red blood cell membranes and cosinophil and endocrine cell granules so that less lysis occurs than with Bouin's solution.

HRP Stabilizing Diluent is an aqueous MOPS Buffered solution that has been developed specifically for the stabilization of Horseradish Peroxidase conjugates in solution. HRP Stabilizer prevents the loss of catalytic activity and maintains the conformation of the antibody or protein antigen portion of the conjugate for up to 18 months. Our product is filtered at 0.2 microns.

This product has been developed to increase significantly the shelf life of diluted peroxidase-labeled proteins. Stability is increased at room temperature storage conditions in addition to 2-8 centigrade. This product is subjected to 0.45-micron filtration and contains no mercury or azide.
Our formulation insures consistently high levels of activity for both the enzyme and the antibody following long-term storage at final-use dilution. HRP Stabilizer greatly improves the signal-to-noise ratios, increasing immunoassay sensitivity and offers cleaner assays. This product has been chemically engineered to increase conjugate stability providing the a longer shelf life, resistance to various shipping conditions & storage temperatures and improved day-to-day assay precision.
HRP Stabilizing Diluent is highly recommended for use in ELISA development, in conjunction with Teomics's proprietary Coating Stabilizer, IncrediBlock Advance, Washing solution, TMB (high sensitivity) and Stop Solution.

IncrediBlock Advance is a unique serum-free protein block for immunochemistry. IncrediBlock Advance eliminates the need for matching species with the secondary antibody (such as when serum is used) and is often more effective at reducing non-specific background staining than normal serum. This product is useful in a variety of applications where antibodies are used, including immunohistochemistry, ELISA plate blocking, and western blotting.
$ 45.00
IncrediBlock Advance Free is our newest serum-free protein block (without casein) for antibody-based applications. There is no need to match species with the secondary antibody is eliminated due to the lack of normal serum in this product and is often, more effective at reducing non-specific background staining than normal serum.
$ 59.00
IncrediBlock Basic is a highly optimized protein block for antibody-based methods, simplifying immunohistochemistry, ELISA plate blocking, and Western blotting methods. IncrediBlock Basic eliminates the need for matching species with the link antibody and is often significantly more effective at reducing non-specific background staining than normal serum.
