<prompt> The sensitive stain used to stain copper in Wilsons disease is:Timms sulfideRhodamineRubeanic acidTrichrome stain  <response>: The copper is stained with rhodamine and rubeanic acid stains. More sensitive stain used is TIMMS SULFIDE. It is more effective in detecting cytoplasmic copper binding proteins. Trichrome stainning is used to show fibrous tissue. ALSO KNOW: The rhodanine stain is used to demonstrate excess copper in hepatocytes in Wilsons disease and also to demonstrate copper deposition in chronic biliary diseases.
