Haemin is a porphyrin chelate of iron, derived from red blood cells; the chloride of haem[1].
DISCOVERY
The Polish anatomist Ludwik Karol Teichmann-Stawiarski discovered haemin crystals in blood in 1853. The method[2] is as follows:
• Acetic acid was added to dried blood.
• The solution was dried at a temperature of 25-62.5 degrees Celsius.
• Upon observation through a microscope, rhombic crystals of haemin
were seen.
Below is a photomicrograph[3] of haemin crystals:
