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

Description
Our kit is designed for staining myelin/myelinated axons and Nissil substance on formalin fixed, paraffin-embedded tissue as well as frozen tissue. Our kit is used for identifying the basic neuronal structure in brain or spinal cord sections, and contains a Cresyl Echt Violet counterstain. Using our protocol and the modified formulation, myelinated tissue can be stained in as little as 30 minutes.

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.

The Calcium Stain Kit (Modified Von Kossa) is intended for use in the histological visualization of calcium deposits in paraffin or frozen sections. The Modified Von Kossa method is a precipitation reaction in which silver ions react with phosphate (not calcium) in the presence of acidic material. Photochemical degradation of silver phosphate to silver then occurs under UV light illumination. Tissues are treated with a silver nitrate solution and silver replaces calcium reduced by strong light, and so can be visualized as metallic silver. To confirm the presence of calcium, Nuclear Fast Red solution is used to confirm the presence of calcium deposits.
Calcium in mass deposits: Black
Calcium in dispersed deposits: Gray
Nuclei: Red
Cytoplasm: Light Pink
