Robert Feulgen died in 1955.
Robert Feulgen was born in 1884.
The Feulgen stain is specific for DNA as it targets the deoxyribose residues in the DNA backbone. The stain reacts with the aldehyde residues in DNA to form a complex that fluoresces when exposed to UV light. RNA does not contain deoxyribose residues, so it does not bind to the Feulgen stain.
