Name	Comments	Products	Part #
Copper	Some methods demonstrate copper associated protein rather than copper itself	Copper Stain Kit Control Slides	9113 4130
Hemosiderin	Prussian Blue reaction stains ferric (+3) ions	Iron Stain Kit Control Slides	9136 4320, 4321
Hematoidin	Similar to bilirubin often formed as a result of hemorrhage, stains with bile methods but not with iron methods
Bile	Demonstrated when bilirubin is oxidized to biliverdin in an acid staining environment	Bilirubin Stain Control Slides	Procedure 4060
Calcium	Black deposits formed when using silver reactions are due to reduction of silver by organic material followed by exposure to strong light	Calcium Stain Control Slides	Procedure 4100
Urates	Both forms are water soluble, aqueous fixatives should be avoided Absolute ethanol is the fixative of choice Gout – monosodium urate crystals appear yellow when their long axes are aligned parallel to a red compensator filter Pseudogout -calcium pyrophosphate crystals, appear blue when their long axes are aligned parallel to a red compensator filter	Urates Stain Control Slides	Procedure 4700
Melanin	Identified by a number of methods can interfere with pathology interpretation if found in large amounts	Melanin Stain Control Slides	Procedure 4430
Lipofusin	Stains variably but usually PAS positive	PAS Stain Kit	9162

Artifact:

Carbon	Inert and unreactive, resists removal procedures, commonly found in lung and mediastinal lymph nodes.
Melanin	Can become problematic in large amounts and be removed by a variety of methods	Tech Memo
Formalin	Formed in unbuffered formalin when pH shifts to acidic, not reactive with iron staining methods	Tech Memo
Mercury	Deposited as a result of using mercury based fixatives	Tech Memo
