What is hemosiderin?

Answer 1

A golden yellow or yellow-brown insoluble protein produced by phagocytic digestion of hematin; found in most tissues, especially in the liver, spleen, and bone marrow, in the form of granules much larger than ferritin molecules (of which they are believed to be aggregates), but with a higher content, as much as 37%, of iron; stains blue with Perl Prussian blue stain.
