Spirochete: Silver Staining for Nucleic Acids
Borrelia burgdorferi the Lyme disease spirochete was grown in modified Kelly medium and characterized by transmission and by scanning electron microscopy. Using silver staining procedures which preferentially bind to nuclear components of eukaryotic cells, signal could be detected by backscattered electron imaging throughout the length of the prokaryotic spirochete. Interestingly, however, the ...
متن کاملNucleic acids and protein synthesis in cancer cell mitochondria. I. Nucleic acids in rat hepatoma mitochondria.
The contents of nucleic acids in rat liver and hepatoma mitochondria and the physico-chemical properties on DNA’s isolated from these mitochondria were comparatively investigated. The results are briefly summarized as follows. 1. The contents of DNA and RNA per mg protein of the hepatoma cell mitochondria were about 10 and 2 to 4 times higher than those of rat liver mitochondria, respectively. ...

متن کاملSTUDIES ON NUCLEIC ACID METACHROMASY II. Metachromatic and Orthochromatic Staining by Toluidine Blue of Nucleic Acids in Tissue Sections
Acrolcin-fixed, polyester wax-cmbcddcd tissue sections showed excellent preservation of light microscopic architecture and, when stained with toluidinc blue, intense color contrast between DNA, which stained orthochromatically, and RNA, which stained metachromatically. This method has practical value for differentiating DNA from RNA in the same section. The color c~)ntrast was impaired by subst...
متن کاملNucleic Acids
The first isolation of what we now refer to as DNA was accomplished by Johann Friedrich Miescher circa 1870. He reported finding a weakly acidic substance of unknown function in the nuclei of human white blood cells, and named this material "nuclein". A few years later, Miescher separated nuclein into protein and nucleic acid components. In the 1920's nucleic acids were found to be major compon...
