What does the Rhodanine method detect in tissue?

Explanation:
Rhodanine staining is used to visualize copper in tissue. The rhodanine reagent reacts with copper ions present in cells to form a red copper-rhodanate complex, which stains areas where copper has accumulated. This makes it helpful for detecting hepatic copper overload, such as in Wilson disease, where excess copper concentrates in hepatocytes and bile ducts. Other metals are detected with different stains (for example, iron with Prussian blue, calcium with Alizarin Red or von Kossa, zinc with zinc-specific stains), so the distinctive red color from this stain indicates copper specifically.
