The Copper Stain Kit (For Microwave) is a rapid (2 hr) staining kit that is intended for the demonstration of copper deposits in tissue sections, most commonly in cases of suspected Wilson's disease. Wilson's disease is a rare autosomal disorder caused by decreased serum ceruloplasmin, a blood protein that transports serum copper. Ceruloplasmin deficiency leads to excessive copper accumulation in brain, eye, and liver. In the liver, hepatic copper accumulation results in fatty change, acute hepatitis, chronic hepatitis, eventually resulting in cirrhosis. Urinary copper excretion is increased.
The rubeanic acid and rhodanine stains in the Copper Stain Kit are used to stain the cytoplasmic accumulation of copper in the liver.
Copper Deposits: Light Brown to Red
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.
The Acid Fast Bacteria (AFB) Stain Kit is intended for use in the histological visualization of Acid Fast Bacteria and Tubercle Bacilli. This kit is a rapid 15-minute procedure. The lipoid capsule of the acid-fast organism takes up carbol fuchsin and resists decolorization.
Acid Fast Organisms: Bright Red
Background: Light Green
These Acid Fast Bacteria (AFB) Animal Control Slides contain sections of positive staining goat intestine and negative staining human 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 formaldehyde-fixed, paraffin-embedded, heat dried, and cut at 5 microns unless otherwise specified. Standard tissue placement is mid-range of slide.
