Prussian Blue and Turnbull's Blue Stains for Iron Detection

question 1 of 1 course: Biomedical Science(Degree)
question 1 of 1 course: Biomedical Science(Degree)

Q: Which stain is used to demonstrate the presence of iron in bone marrow macrophages (hemosiderin) and sideroblasts?

Did You Know?

This statement is true. The O allele in the ABO system is recessive and does not code for a functional glycosyltransferase enzyme. This enzyme is needed to modify a basic precursor substance (the H antigen) into either the A or B antigen. An individual with two O alleles (genotype O/O) lacks the enzyme to produce either A or B antigens. Therefore, on their red blood cells, only the unmodified H antigen is present. This results in the blood type O phenotype. Their plasma, however, will contain both anti-A and anti-B antibodies because they lack both A and B antigens.
